I need to make it so that no scrap is created in the lower processor, for this you need a block to prevent creation in the processor.

Add a block of the creation black list, create a texture for it, and add an inventory to it where it will be possible to indicate which item it is forbidden to craft in it.

Or add to the interface a function that will allow you to select the processor in which it will create, as well as into buses and similar mechanisms.

Do like this

In short no as this can already achieved by a more creative network setup.
