Sprouts spawn way too often, its like 1 for every Minecraft grass

So for forge you need a datapack while fabric has a config?

there is already away just change the weight in the biome modifiers on forge and the config on fabric

yes because fabric has no official way while forge does via biome modifers

So I remove this entire thing and leave it blank for it to not spawn ?

you put

{
"type": "forge:none"
}

and that will disable it

Thank you for the clarification
