Minecraft wiki entry for Gathering_resources_on_peaceful_difficulty, associated text: Although endermen don't spawn on Peaceful, ender pearls can be obtained by 3 other means. Ender pearls can be found in the chests of strongholds and woodland mansions. Both of these structures are very rare, but woodland mansions can be found using a woodland explorer map, although the nearest woodland mansion could be very far away. Two ender pearls always generate in the fake end portal room chest, but not every woodland mansion generates a fake end portal room. You can also get ender pearls by giving a cleric villager 5 emeralds. If you have a farmer and a large wheat, beetroot, potato, or carrot farm, you can gain lots of emeralds by trading these items with the farmer, and thus gain lots of ender pearls. You can also get ender pearls by bartering with piglins. Despite the fact that ender pearls can't be used to make eyes of ender because of the lack of blaze rods, ender pearls can be used to teleport, which can be very useful at times.
