I am using the CraftTweaker with NEI, I have a script that removes items from the list of NEI. Some code:
import mods.nei.NEI;

NEI.hide(minecraft:mob_spawner:*);
NEI.hide(minecraft:spawn_egg:*);

But the deletion does not happen the first time, for example, when you enter the server or in a singleplayer, the deletion does not happen, although the log says that the deletion was successful. I would like to see support for the crafttweaker in this mod.

same problem

you can download latest version of nei gtnh and hide all spawner and spawn egg
