I have no idea why they haven't added a config option or something to the mod to make it so that you could do this without having to use a datapack or edit the mod jar file itself, but whatever. 🤷
I've tested this on 1.21.1 on Neoforge, and it seems to work just fine for me there.
Any other versions past Minecraft 1.19 of Epic Knights / Magistu's Armory that also happen to have the exact same filepath to the steel ingot blasting recipe file in this pack should work just fine too, just the same as all other data packs that use the method i'm using to get rid of the recipe here.
