Russification of the global version (Assassin's Creed: Valhalla)

It just so happened that I got the PC version of the game without Russian (there is Polish, German, English and other European languages, but no Russian). The support of the yubiks answered that there is no official way to add a locale - only buying another version of the game that includes the desired language. How can you unofficially localize but keep the online component of the game (achievements, etc.)? if you prohibit the update and replace the yupley with a rip from a torrent - will it help? I don't really want to experiment so as not to get banned.


ps on the bourgeois forum I found a thread discussing the angloification of the Russian version and there they spread ready-made replacement kits, googling did not find my solution problem
