How to remove vanilla biomes 2023.3 EAP 33711

I'm making a mod that changes every biome, and adds new ones. The best way I imagine doing this is to remove and replace the vanilla biomes altogether. I've looked through the forums, and saw others have asked this as well, but they never got answers that worked for me. I'm willing to use code for it, as I know you cant do this with drag and drop. I'm not willing to simply teleport the player to a different dimension that resembles the overworld, as I don't believe it will work for my purposes. Plus, there are many issues that could arrive with that option. If you do end up giving me code to use, please also add where to use it. Hope these are enough details, if you need any more please let me know. Thanks in advance.
