Trying to edit cave biome sizes in an existing datapack

I am trying to increase the sizes of the biomes in the Spelunker datapack (https://www.planetminecraft.com/data-pack/spelunker-1-18-by-ptrn23-alpha/) I have tried editing the temperature and vegetation xz_scale in data\minecraft\worldgen\noise_settings\caves.json, but that only seems to effect a few biomes (spelunker:honeycomb_quarters, spelunker:frozen_soul_chasms and spelunker:amber_resin_caves). I'm specifically trying to increase the size of the default caves, as well as the dripstone caves and the radioactive fallout caverns, while leaving the size of the other biomes relatively small. Any help is appreciated
