Question about steam games

My computer MOBO recently suffered a failure and I am waiting on RMA repair/replacement, but I plan on buying a metaquest 3 that will arrive within two days.

Is it possible to download games via steam directly through a VR headset without the use of Steam on a PC, or is that not possible? I would prefer to attach games to my steam than to a meta account as far as purchases go, but if that is a requirement then it can't be helped.
