I highly recommend using a mod manager like ThunderStore to manage your mods. Makes it much easier to update, configure and dis-, enable them.

That said, Valheim+ is supposedly the mod where you can change a lot of the settings in a configuration file (which is made much easier via ThunderStore).

Caveat: I never used Valheim+, but a lot of people seem to. It's available through the integrated mod downloader in the ThunderStore mod manager.
