So, I've been making a modpack that includes Ars Nouveau and would like a method in configs to disable specific mechanics, namely warp portals as a way to create permanent portals everywhere makes other travel systems completely redundant, and I would like a way to disable warp portals without having to remove the recipes for warp scrolls, as they have other uses, or arcane bricks, as they make for good decorative blocks.

For portals, you can disable them by removing the blocks from the an_decorative block tag. That is used by portals for valid blocks.
