Monsters only in Ruins and story structures

Is it possible to somehow implement the customizable spawn of rusty monsters? I wanted to explore the mines without fear that the ruins and plot locations would bring horror.

There are mods to reduce spawns in general, or make monsters spawn only underground, but I'm not sure that there is one to limit monsters to story structures and ruins only. If fighting monsters is the issue, you might have better luck either using a mod to reduce spawns, or setting creatures to "neutral" so that they'll only attack you if you attack them first.
