Remove water from carver caves under oceans

I am trying to remove water from non-noise caves under oceans (pre.1.18 ones, think that's what they're called) Things I've tried - - setting barrier to -1 in noise settings - setting fluid_level_floodedness to -1 in noise settings - setting fluid_level_spread to -1 in noise settings - for the above three items, keeping the original values but setting xz_scale and y_scale to -1 - creating aquifer_barrier.json, aquifer_fluid_level_floodedness.json, and aquifer_fluid_level_spead.json and setting amplitudes to [0] Any suggestions? 🙂
