As I understand, the Quest 2 can support VIVE's Deluxe Audio Strap, with
some modification, though this is now an old and discontinued product.
Logitech also have a partnership with Oculus to offer compatible

A cheaper workaround would be a Steam Deck. It may never compare to
using a PC in performance, because the device is not optimised as a VR
bridge, but it is still an alternative.

preparing to do that, however, a mandatory login makes no sense to me.
You are asking the wrong company - it is ultimately up to Valve whether
their games are remastered. That being said, I do agree they should
offer VR support for a new generation.
