I am doing a modpack, and I have enough of those biomes that are already in the nether and in the end. I've tried many different ways to disable BYG end and BYG nether, but nothing works (at least with nether).
I am also using the addon "All The Biomes You'll Go" version 1.1.0

If our config doesnt work, another mod has taken control of the nether, use their config
