I looked into it maybe a month ago and the answer was still no. Game Pass for PC (Microsoft Store) games are encrypted so you can't just install/run them on a compatibility layer like Proton. Unless of course you mean XCloud Streaming. Otherwise your best bet is just pirating those games ig.
The new executable format that window store apps seem to not work with wine. They seem to be a very different format from exes and are encrypted, so that's going to be a tough egg to crack and a lot of work.
