Remove Bottom Lava from Generation

I want to make a datapack that removes the bottom-world lava from generating. I have already removed lava lakes and lavafalls, but those don't count for the lava layer at Y=-55 and Y=-63. Even removing caves and disabling Aquifers doesn't seem to remove the lava pockets.
I am on 1.21.10 using Fabric with performance mods.
-# I've tried messing around with Misode's generations but the terrain preview seems to be inaccurate and doesn't correctly display some things, and i tried just doing random shait but even when it seemed like I had placed a solid range of "terrain" caves would still generate (I had like an hour obsession and just fukd around with noise settings for an hour lol)
