Used to have a Vive in 2018, bought a bunch of games for it on Steam but moved and didn't end up setting it up again so I sold it. 
Just got a Quest 2 the other day. Love it and had to get the official Oculus cable to link to the PC without it disconnecting me every 5 minutes on a 3rd party cable so I could play my steam games without using AirLink (I want to use my PC hardware (3070, 5900x)). 
My question is that is there a way to upload Steam games to the Q2 without having to link? I know about sidequest but that's all Oculus native shit. I just want to be able to play a couple steam bought games while I am away from home without my PC or internet. I keep trying google but it seems as though it's not possible...
