Very few Zombie piglins

Hello, in the nether weast a very very limited amount of piglin zombies are generated which causes it not a challenge to fight them anywhere, besides that when it comes to wanting to make a gold farm in the nether the generation cup is very very low which consequently makes the production so is , the gold farms used was taking advantage of a meccanic from the portal to nether but this broken in Caves and Cliffs update, if you could do something I would appreciate it very much, have a good day good mine!
