The only thing I can think to do is download an uncensored patch for the German version of the game and run it on top of this mod, this may or may not work I don't know.
I have the link to a patch download page here: Call-of-duty.fandom.com, but all the instructions are in German so you might have to sit there with google translate for a while and decipher the instructions.
