More Mobs x Incendium mobs compatibility?

Hey everyone! I just installed More Mobs by Tschipcraft and everything is great except I noticed one issue when paired with the Incendium Nether overhaul. The Wither Skeleton variants in the More Mobs pack overwrites the "Headless Warrior" wither variant that the Incendium spawns in Incendium's "Withered Forest" biome. Is there any way I can fix this? Could maybe simply disable More Mobs from being activated in said biome? Just not sure how or where to start so would really appreciate any and all guidance
