yes, but they don't spawn at default like-live spots. more like hot zones. for example in factory they spawn in the middle of the map. i did not find any settings for this in f12 menu
May have to mess with like zone caps, or change the coordinates for spawns in one of the configs files. I've never messed with that because I've never seen that happen really. Only like on Customs when it was on Random and it would bug out and spawn like 10 Scavs in one area with bosses because it was like stuck on boss invasion or something, even when it said it was like live-like.
