Modding might not be as easy as on Windows, but for example, Mod Organizer 2 works on Linux. Steam Tinker Launch helps with MO2 installation and usage. Wabbajack also works after some tinkering, but you’ll need to search the Internet to figure out how to get it working.

Once you go through the pain of getting one modding tool working, you can then use it with other games without the initial hassle.
