Use diffrent dimension.json based on if a mod is installed

[LeTrav]

I currently am trying to developing a mod that creates a copy of the overworld, (that was pretty easy). The hard part is I want it to be compatible with terralith. To do so I need to have my world use there dimension.json if terralith is installed. Is there a way I could pass a Predicate to the dimension.json to override the properties of it? similar to how ItemProperties works?

My original thought was to define a new resource location and use a different named .json file, However that fails due to terralith using  custom biomes that dont exist when terralith isnt installed.

define and register the dimension in code. Then you can do that

Would you be able to point me in the right direction to do that? I'm still pretty new so I'm not sure where to even begin with that. Plus forge documentation is not very helpful.
