Skorpion Gamer helped me in this case sharing the commandline he used to block game forced update on launch :)
So, now the zip contains a commandline.txt that would allow you to open the game in offline mode avoiding forced update.
Steam backup of .exe only:

Steam backup with update.rpf:
https://mega.nz/file/JBw3mYiD#ZlvSjK25n6f9gph-RVUn6OG5i_FYZk236DsT05AX6Vc
Let the game update the files normaly, then close the game, apply the backup including the commandline.txt and launch the game.
Obs.: This is for Steam version only, Rockstar launcher or EGS version won't work :(
