I'm having the same issue and I'm using bg3 Mod manager. I want to use an older version of a head I like because the new version no longer supports Unique Tav but every time I start up the game the newest version will be installed. I deleted it & then replaced it with the old version several times, deleted it out of the mods folder & tried deleting it after I logged out of my Larian account but it keeps coming back. It's just annoying and somewhat tedious to replace it every time I try to load up the game.
