Help with making armor take less damage from certain mobs?

I've been using Mcreator for making a (joke) mod for quite some time, and I wanted to make an armor piece that doesn't give armor points, but takes less damage against Pig mobs (Piglin/Zombie Piglin/Hoglin/Zoglin) and it's been a little difficult figuring out how to make a procedure that could achieve that for me, anyone able to help me here?
