very niche but i think it deserves a mention:
the Outer Wilds mod manager doesn’t just support Linux natively, but it even has a CLI version, and it’s up on AUR and Flatpak
as others have said though, r2modman/thunderstore manager also runs in an appimage and works perfectly well for games it supports, and MO2 and Vortex work more or less alright if they’re in the same prefix as your game or potentially even if they aren’t.
