DLC MISMATCH fix, Impossible without updating through rockstar?

Is it not possible to update the game via another source to be compliant with FiveReborn? I have my single player game modded, so updating the game will overwrite current mods that I have applied…which I do not want to do. Is there an optional way to download the necessary files to run with fivereborn without getting the error? Even though I do have a separate “MODS” folder to differentiate the modded files, as im sure you know…this does alter any mods updating the game via rockstar to their vanilla.
