I jumped into the Minutemen quests a bit too eager and have control of just about all of the settlements. I'm regretting it now as i just like one or two locations, but the frequency of them being attacked is so low i haven't defended my favorite location once.
I'm wondering if i can reduce the population of some settlements back to 0, and then remove the recruitment beacon. Should that prevent them ever growing back up, and also would that mean them not being attacked?
If thats possible, can i just go and kill them? I'm worried that pre-existing settlements not founded by me have essential NPC's that can't be killed.
