You can't because of the way that samsung implements their power menu. But there are shortcut opener apps on the Google play store which will allow you to enable the game so they pop up in your notification tray. But you have to go into the shortcut opener app to like feed them and stuff.
Edit: this is the app I used https://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite Just search easter egg and go through them to figure out which one is the right one
It's not easy to turn the phone part off on a phone, no. You could dial *#*#INFO#*#* and flip the switch for "Cellular Radio Power" but that's not any more elegant and I see no reason to do that over using Airplane Mode. *shrug* maybe there is a direct option you can find using an app like https://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite to do that same action.
I realize I'm hella late responding (and this probably won't help your issue anyway tbh) but in case you still want to try or for anyone else who may find it:
The reason that dialer code doesn't work for you is that USCC long ago seems to have instructed Samsung to disable such codes in the firmware for their carrier branded devices. It's been this way with every USC Samsung Android I've ever seen - hell, almost every carrier branded USC Android period. BUT...
Grab an app called Shortcut Master Lite (https://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite). Open it up, click the three dots and select "Search...", then enter the word radio. It should bring up an entry that says "Phone Services / com.android.phone.settings.RadioInfo." Select it and press the Launch icon that appears - and just like that, there's the hidden Radio Info menu that "The Man" wants to shut you out of.
...But I doubt it does much good for you, because I have the S22U also and my defaults were already exactly what has been suggested so yours likely are too. (And I've never yet seen a 5G signal even once with this phone!)
You'll have to do some research to figure out where exactly you'll need to navigate to to create a shortcut but this app is best for bypassing greyed out or blocked apn settings.

This should work. I didn't need to add tethering since my carrier allows it but this did give me the ability to edit my APN settings without root:
They haven't yet been discussed online from what I've seen, I have found these on my own.
Get an app that can launch private activities. Shortcut Master (Lite) works well.
The app has a search functionality built into the 3-dot menu. Use that to find MessengerInternalPreferenceActivity
.
Shortcut Master (Lite) has ads in it, the first time you launch an activity, it will pop up a full-screen ad. Close that, and launch the activity again.
In the Internal menu, find Gatekeeper Override.
Look for "intern" to find messenger_internal_prefs_android
and toggle it to true. This will enable the Internal menu in the options screen of Messenger, along with many internal shortcuts when you long-press the icons on the home page. The "People" tab on the bottom (if you have it) will open the Gatekeeper Override when you long-press on it.
Here's some gatekeepers you can enable and are useful:
android_messenger_chathead_typing_indicator
- Chat head typing indicator
android_messenger_enable_high_quality_photo
- This will enable an option in the Photos and media settings to send high quality photos when on WiFi, or at all times.
android_messenger_show_video_size
- This will show video file sizes in threads. Useful when on a limited mobile data plan.
messenger_4_overall_android
- This used to work on an older version of Messenger, but they've now moved it to MobileConfig, which is no longer available since v127 of Messenger. This is the new re-design that they've shown to be working on.
MobileConfig is a section of the internal menu that I would consider the "main A/B testing control". That section controls all the features of the application you can possibly get. You used to be able to disable all of the My day stuff inside it. It made it to the front page of XDA News, which then spread to Facebook itself and the devs blocked the MobileConfig editor client-side. Nobody has managed to re-activate it so far.
When MobileConfig was still a thing back then, I could also edit the colors you could choose for threads, and it included a property called wallpaper_color
or something similiar, that would let me edit the background color of the threads, though it did require the other user to have Messenger closed while I would switch the color, due to an agressive color-checking mechanism. I still have some threads with a custom background color applied. This no longer works on older versions of the app either, they're now handling thread colors differently, probably due to the new redesign that's about to come.
If you install the app Shortcut Master you can see what the secret codes are and what all the secret menu pages are
use shortcut master and search for "apn"
