It's a bit like asking "can I buy Elden Ring on Steam and play the game on my phone?".
No, you cannot - at all.
The Quest 2 has an extremly slow phone gpu (Adreno 650, part of the XR2 SoC), so you're basically playing VR games on a phone.
If you want high-end VR games, like those on Steam or in the Meta Rift Store, you'll need a fast gaming rig - the faster the better. A gaming pc with a RTX 3060 Ti video card will be a great choice though - or something even faster. Unless you're happy with the very low-end phoneVR.
