hi, i was browsing the config in search of a way to directly disable the worldgen of specific ore, but i noticed that there isn't one.

the only option i have found are rarity (wich have a min of 1, so no remove i suppose?) and the biome option, wich seems to behave like a "specific biome vs all biome" kind of thing, right?

is there a way with those option to disable ore worldgen?

if not, i wanted to suggest to add it, to give more freedom to modpack dev to tweak the pack

You can set the veinSize Parameter to 0, and the ore won't be generated anymore.
For example with this kind of configuration Astral silver shoulnd't generate in the world anymore:
