You can use a Oculus Account (not connected to facebook) and then use Virtual Desktop to stream the game from SteamVR over Wifi. If you have a Wifi 6 router it's the best PC VR experience you can have (wireless, no base stations, really high resolution, very low latency) and besides the Quest 2 and Virtual Desktop you are not giving any money to Meta. If you are worried about battery life, I already player with a battery bank in small backpack without any problems! Absolutely awesome.
