You don’t have to add them as non-Steam games. You just have to make sure your desktop profile is set up to match how you want those games to be played. You can save templates and swap them out for a bit easier flexibility.
I have my original Steam Controller set up to swap between a mouse and keyboard mode and an Xbox layout and that works for the majority of things I want to do outside of Steam with it, no fiddling with the “add a non-Steam game” stuff.
