"USB C Dock". I hate to not be able to give you more information on it. I think most of how it works is universal, so just about any usb c would work. Just make sure it isn't Thunderbolt 3 only, those are very architecturally different. Bonus points if the description says that it works on some Android device. Here's an example of one that should work just was well. https://www.amazon.com/UGREEN-Charging-Adapter-Station-MacBook/dp/B07RW343WG/ref=sr_1_6?dchild=1&keywords=usb+c+otg+dock&qid=1594913205&sr=8-6

I am a co-host on the bi-weekly PineTalk Podcast, a PINE64 community podcast. This is pro-bono community work and I try my best to make sure that this work does not affect my views and opinitions on PINE64 products or competing Linux Phones/handheld devices in any way.
For something like that you'd need a device similar to this: https://www.amazon.com/ALINX-AX7A035-Artix-7-Development-Downloader/dp/B08FYB4RPQ/
There's no reason one couldn't be created, but they'd be even more niche than the rest of the Pine devices.
