It is possible, if you manually configure a settings file. I saw some reddit posts where some guy has open a ticket to ask if it's banable or not, and they said it isn't. Bad part? when you turn crossplay off via the settings file since not all players are tech savvy you'll get matched only with the ppl on PC that have the option turned off and never match you with PC players that have it on, and all that result in having lobbies with tons of bots and few players. I've saw lobbies populated 60 or 40% populated with players and the rest bots, but **bleep** the game felt good. No bullet registration issue, no 0.5 ttk BS. I've just made a post about the same issue.
