Looking at the config there doesnt seem to be a way to prevent Items from being loaded and neither to disable Recipes. Or at least I catn find it.
Therefore is there a way to disable Recipes of Seeds, e.g. via CraftTweaker or anything like that?
Also will there be a config to disable certain items/seeds like it used to be possible in 1.12.2?

• You would edit recipes using datapacks
• You aren't supposed to be able to disable blocks/items, that being said something similar is planned but would be with an addon mod

You can now create, edit, or disable crops using my new addon Mystical Customization in 1.15.
