Need help with Armadillo infestation farm

I'm building a basic version of this farm in one of my worlds and I'm at the point where I've been instructed to get a Zombie near the Armadillos to have them enter their scared state(curled up) My question is could I use a Zombie Piglin?

From what I remember I think the requirements we're either A. An undead mob or B. Hostile Undead Mob in the case of it being B then the Zombie Piglin wouldn't work as it's a neutral undead mob until provoked
