Steam Tinker Launch is a versatile Linux wrapper tool for use with the Steam client which allows for easy graphical configuration of game tools, such as GameScope, MangoHud, modding tools, and a bunch more. It supports both games using Proton and native Linux games and works on both X11 and Wayland. An incredible wrapper with a menu that lets you easily toggle and modify various settings for games on Linux. Anything from proton versions to startup and exit scripts, proton/dxvk/etc. settings, FSR, reshade, and even options for various tools like game mode, replay-sorcery, game scope, etc. Tons more too. I just set my default proton version to "steam tinker launcher" and then every game launches with a 2-second menu that allows you to easily change any of the settings. If you don't press any buttons it just goes with the defaults and launches the game.
