I expect this should be enough, but can't test it. If someone can give it a go and tell me if its good that'l be great

# loot.js
if (feature('Replace white ingot (iron ingot) with white plates')) {
  LootJS.modifiers((event) => {
    event
      .addEntityLootModifier("minecraft:iron_golem")
      .replaceLoot("minecraft:iron_ingot", "create:iron_sheet")
  }); 
}
