How can I make a Mod's World Generation generate in a Modded Dimension rather than the Overworld?

I am a datapack beginner and I am trying to accomplish this for a modpack of mine.
I am using mods such as Alex's Caves, Splunkery, and Advanced Mining Dimension. My goal is to have both of these cave mods to generate inside the Advanced Mining Dimension mod instead of the Overworld.
Is this possible? If so, how can I go about doing this?
I am using the 1.20.1 version of Minecraft.
