Option to disable vampires?

I suppose I wouldn't be bothered if there was a toggle, it might be completely impossible the way the game is coded, or it may be more possible than making it an open world after all this time. Though I really hope there isn't any toning down some are seeing way more vampires than I am so it could be a slight glitch that needs to be tweaked however I would hate thinking I paid for vampires and then they were accidentally tweaked too much. Comparing them to aliens a lot of people saw way more activity from them than I did but I did see some now I only get them if I add them in and there aren't any abductions at the moment, they were just an add on so fine. I remember in TS3 a lot of simmers had my issue with the toggles, turned everything off but all it did was shrink the amount that spawned leading to more routing issues making the toggle pointless. I was thinking it was nice that they got their own pack so anyone who didn't want them could just save themselves the twenty bucks and not have them at all ah well. Sure I understand but at the same time they were not just an add-on.
