Yup. Install either Heroic or Lutris (though Heroic is a little better). I think there’s also a plugin to allow you to access Heroic through the Steam frintend, but in Desktop Mode, when installing a game through Heroic, it’ll add it to your Steam library, which means you can access it in Game Mode too.
Well, “owning,” if they’re bought through Steam.
Does the Steam Deck have GOG support?
You can sideload a program called Heroic Games Launcher that lets you easily manage your GOG games, as well as Amazon and Epic.
You can download it through dicvover in Desktop Mode.
