I haven't used the Quest 2, but I know a few people here do. I can only tell you about the Steam side of things and that I'm not sure they ever fixed the battery drain issue. Your USB-C is better off using a battery and using a wireless hookup to your PC via either Airlink or virtualdesktop. 

Again, it's entirely because IIRC the PC can't actually fully power a Quest 2 like it could the Quest 1 so you'd just run the battery dry quickly anyways. It doesn't hurt to get more information from someone keen on learning it though.
