Piglin Brutes enchantment drops

As a reward for defeating a piglin Brute, they should drop a special enchantment book that is called pyrite that allows you to enchant a piece of armor with is that functions as a piece of gold armor when it is not so netherite can have the pyrite enchantment but function as a piece of gold armor so pigins do not attack you. It means that you can not explode the brutes or shove them into lava because the book would be destroyed if that happened.
