How do I disable netherite entirely?

So I've searched all over Aternos and the web and I have not found a SINGLE plugin for disabling Netherite entirely. I'm not sure if Better Netherite would work, but either way it's 1.17.1 only or something. I REQUIRE this for my SMP infact I have 3 days. Please find me a plugin or config option to disable it.

Thanks.

Alright nvm I found out I can use a goddamn item ban plugin.
