Bot lobbies when crossplay is off (XSX)

I'm in the UK and come 10pm or so when I have crossplay off I get straight into a game lobby and it takes a while to populate, so it populates with bots. The moment I turn crossplay back on its full lobbies again. Can we have it to console only crossplay. It's only PC I want to turn off.

Majority of my gaming is done after 10pm as is most parents/husbands/wives! 

I can play with PC. I just prefer not too. I have a lot more bad games when playing with PC. A few PC would be fine but not an entire team of 32 PC players. That stuff gives me nightmares and BF6 PTSD
