Need help with NPCs wars

I want to make a NPC war but I have no idea how make NPCs ignore you so they won’t shoot me on sight. So I was wondering if anyone knows the console command for it.

Use notarget

You can also use ai_disable to make them stand still and not shoot each other until you finish the npc’s placement.
