Which crack for RDR2 (Steam download)?

Hi guys, which crack could I use for a Steam downloaded Version of Red Dead Redemption 2? I got it through steam share from a buddy but he‘s constantly playing it and since I‘m not interested in the Multiplayer side I wanted a safe cracking methode so I could play it offline. I don‘t want to re-download the entire game just to play it cracked. Any tips? Thanks in advance!
