How to add a new biome to the nether in 1.16+?

[Beethoven92]

What the title says, just wondering if there is a way to add a new biome to the nether without creating a custom world type, which is the way biome o' plenty is doing that (to pick one). Its simple to do that with the overworld dimension, but i really cannot get it to work with the nether...Thank you very much
