Undead Army Config

[KryoXMusic]

Is it possible to config the amount of undead you need to kill in order to summon the army/turn it off completely and only leave the banner? If yes, I can't quite find where said config would be. I have a modpack where there's hordes of zombies already swarming the base at night, and it gets annoying having to fight a raid every time I try to get rid of it, yet I like every other feature of the mod and wouldn't want to remove it.
I'm on 1.20.1, v1.9.10 of the mod.

I wanted to config the required game stage of the event to be triggered too. Using the same version 1.20.1, v1.9.10.
