Changing "when dungeons arise" biome settings

Hey guys, so idk if this is even possible but Im trying to find a way to change the biomes for the "when dungeons arise" datapack. I have a custom world generation plugin on my server (Terra) but all the biome names on there have custom names. Like a plains biome is now called "plains_zero". So im guessing thats the reason as to why dungeosn arise isnt working rn. I've looked through the .json files but im not seeing about changing biomes, but Ik its possible as I've some other youtuber do it with there server. So if anyone has any ideas how to do it, I'd love to hear it
