Vive and Index support Steam for Linux. Not many native games though and Radeon support requires bleeding edge Xorg, Mesa and kernel. Some games do work over Proton. A bit telling that even Alyx isn't sporting native support right now even though Valve has brought all their other games over.

There are some people who did GPU passhtrough to W10 quest but I think there were numerous issues like audio over displayport, motherboard pci-e iommu grouping and resetting Radeon cards.
