This datapack replaces all of the Immersive Engineering village structures with blank ones that are too big to generate.
It does not remove IE's villagers, the best solution I've found for that is to disable all of their trades with Custom Villager Trades.
It can be installed like any normal datapack, or you could use mods like Open Loader or KubeJS to load it like a normal mod by extracting the "immersiveengineering" folder into the "data" folders from either one of those mods.
This should work on any modern version of IE as long as it has the same structures as the 1.18 version.
