Ahhh I see what you're asking now. Sorry, I misunderstood.

Yeah, I think you'd have to run Windows :( Even if the games were supported via Proton, I think (but I'm not sure) that Gamepass adds its own DRM layer.

If you do have a separate Windows machine though, streaming actually works very well... better than the Deck on its own... better graphics, way less heat/fan/battery life consumption (since the computer is doing all the hard work). I'd try if you haven't already.
