version 3.2.29

So
current recipes:
4 Soul Sand = 1 Soul Sandstone
1 Soul Sandstone = 9 Soul Sand

i want to change the recipes from "1 Soul Sandstone = 9 Soul Sand" to "1 Soul Sandstone = 4 Soul Sand" but i can't find anywhere in the config to disable or change the recipe and i cant remove the recipe with crafttweaker
