FM Weapons Pack without insane spawn (STALKER: Shadow of Chernobyl)

Good day, I want to ask smart people, is it possible (and how to do it) to remove the spawn of all kinds of warring NPCs in the mod for PM FM Weapons Pack? I play on a laptop and this constant spawn slows down the game, but I want to play comfortably. So, I want to make a simple weapon mod, leave all weapons and other items, and cut out the mad NPCs who climb out from behind each bush and kill each other.
