The bug

When creating custom world using a datapack, there is an option in the noise settings called noise_caves_enabled. When this option is set to false, the noise caves still generate. 

The expected behaviour is for the noise caves to no longer generate.

I have added a datapack to this issue with the settings I used and I have disabled the carvers in the biome files in this datapack.

How to reproduce

1. Download the supplied datapack
2. Import it into new world
3. Generate the world
4. Go into spectator mode and look at the caves, the noise caves still generate
