Minecraft wiki entry for Survival_in_an_infinite_desert, associated text: In (non-Bedrock) legacy console editions, there is no Customized or Buffet world type, but a Superflat world can be customized as an endless Desert Biome. By adjusting the layers it can also have most of the underground structure of a normal Minecraft world. It should be possible to replicate the underground structure of the Superflat Desert Preset of Java Edition.
