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

Invalid/WAI - the given noise_settings/overworld.json file is not functional, so the game uses the default settings. If you use a proper file it will work.
I have found a a way to fix this in the datapack itself. When I replace the line "structures": {} in the noise setting file (data\minecraft\worldgen\noise_settings\overworld.json), with this:
___________________________
"structures":
{ "stronghold":
{ "distance": 32, "spread": 3, "count": 0 },
"structures": {}
},
__________________________
The noise caves are then not generated anymore. I suspect the code reading the json file breaks when the "stronghold" tag is not present.
I hope this helps debugging this further.
