[HELP] How do I reset biome data?

[AzaleaCatgirl99]

I remember doing this before, but I can't figure out how I did it. Is it still possible to select all the chunks of a world and reset the biome data so Minecraft can apply new biomes to the chunks? I'm not trying to reset the chunks themselves, but just trying to make Minecraft re-apply biomes onto the world.

Have you ever found a solution to this?
