so tcon adds its on copper but other mods do that too.

would it be possible to link the ingot nugget and block to the ore generation setting? that way you could disable the items by disabling the ores

You cannot disable items with a config in 1.16. You can change the default output of most recipes with mantle server config, however.

Yep, this is a problem as old as mods, and removing the items is not the solution. You have duplicates? Hide them in JEI, change the recipes.

That is a known bug in Mantle, but that config is just for convenience. Datapacks can already change all our recipes.
