Fair enough man, I personally don’t have one that goes under the desk, I have one that sits on my desk, I got it as a gift and it’s pricey for a headset stand but it has RGB and usb slots so I guess that’s why.
But for you maybe I’d suggest this one?
But if that’s not your style since it’s magnetic and usually goes on the pc perhaps this one might do, just simple under the desk
I’ve linked two on the cheaper side so hopefully that helps abit!
These are the ones I got off Amazon

I spray painted my girlfriends white to match her desk set up. They were a little tricky to find, but on Amazon I typed in “furniture adjustable riser” or something of the likes.
I saw some really cool 3d printed ones on Etsy, they were a little pricy since they’re handmade, but I may upgrade to those one day
