Biome Documentation - minecraft:subsurface_builder

Sub Surface Builders allow specifying a minecraft:surface_builder to be applied to biomes located underneath regular terrain surface. Note, however, that pre-existing surface builder types' processing have not been updated to accommodate the ability to specify them for sub-terrain height ranges, which may lead to unexpected results when using them.

Note

This item requires a format version of at least 1.26.30.
