[1.15.2] How to increase "sea level"?

[Mantoes]

Before I explain, I need any help I can get so if it is not for 1.15.2 that is fine, I just need a better point to start as I am currently very lost.

 

My current goal is to increase the base world height to ~128 rather than 64. Meaning that world gen would be roughly unaffected (if possible) but the stone/cave layer is about 64 blocks taller.

To clarify, just because every post about this is misunderstood, I DO NOT want to increase the maximum build height, that should stay at 256.

 

The goal is to have more stone that can be split into layers, which I have already managed to do, except with layers of ~32 it doesn't leave much room for satisfying exploration or mining,

You have to make a ChunkGenSettings class and edit it there, that's how i got my sea level to be different. I'm using 1.12.2 however, so idk how different it will be for you. I've just been following tutorials online, nor do I know much about coding in general. Sorry if it's not much help
