Making a dumb character - Locking default recipies

[icantevenname]

I know that it's possible to have a character know a thing from the get-go,

inst:DoTaskInTime(0, function(inst)
	inst.components.builder:AddRecipe("thingy")
	inst:PushEvent("unlockrecipe", { recipe = "thingy" })
	end)

So what would be the opposite? The idea being needing to use a Science Machine to prototype the locked out recipes.

I'm pretty sure this is possible, i saw code doing this to ensure that a character that has a variation of an existing recipe will not have the original recipe. I hope it can help your search.

Can you point me in the direction of this mod?

No, i tried to find examples but couldn't. I'm pretty sure i saw similar requests in the past, but can't find them again.
