FWIW 95% of the games i play on my Linux are from other stores than Steam: GOG, Zoom Platform (not related to the Zoom telething) and itch.io, all of which are DRM-free stores. The Steam games i buy are mainly from small indie devs that do not have nor plan to have releases outside of Steam.
To play games i use UMU Launcher which is basically Proton minus Steam (or Wine plus DXVK, etc, depending on how you look it at). I use the "raw" UMU Launcher with its own command-line utility, though it can be used as part of Lutris for a GUI-based experience.
