Is there any way for me to disable NPC's in a specific area?

I’ve downloaded a couple MLOs and they some of them are full of NPC’s just sitting down, whereas others don’t have any.

For examply, my Gabz MRPD has none in it, which is great, but I also have the Vespucci PD and that has NPC’s everywhere. They’re in the lobby, offices, interrogation rooms, etc. Is it possible for me to target certain areas to completely disable NPC’s in, while still having them enabled for the rest of the world?
