I posted the following in your discord and someone else suggested i make a feature requested here so here I am :)

I'm using incontrol to prevent certain mobs from spawning based on ylvl and i am also using enhanced celestials to create blood moons. Is there a way I could add like an exception to spawning if cause by a mod? sort of like you can do an exception with spawners.

,
{
"minheight": 60,
"spawner": false,
"mob": [
"biomemakeover:decayed",
"minecraft:zombie",
"minecraft:husk",
"minecraft:zombie_villager",
"minecraft:skeleton",
"minecraft:drowned",
"minecraft:glow_squid"
],
"result": "deny"
}

That's not possible I'm afraid. I have no way of knowing what mod caused a certain mob to spawn
