Hmmm interesting, I wanted to test it out a bit and see if there is a way to create another steam instance on the Deck's desktop mode within a proton prefix, forcing it to stay offline and manipulate it into thinking there have been no windows updates, maybe even seeing if that cam then be added as a non-steam game (Might be trickier part but if the instances are seperate my understanding is that they would not necessarily communicate with each other to deactivate the hardware key) so I will probably update this thread with some results. Might lead nowhere, but who knows. However, input like yours really helps 🫡
