Minecraft 1.18.2

At the moment I am developing a military-political Minecraft server with mods in the style of the Victorian era with a map of the real world.
And if the impossibility of digging ores in the ground can still be re-realized, then the lack of veins of ores and oil completely destroys most of the mechanics.
Is it possible to generate new ore veins, or at least install them yourself?

he want to regenerate or autogenerate new ore veins

I don't understand this question.
Can you try to explain this again?

Mineral veins are created at world creation. Just like ores would be.

You can add additional veins to the world by using the /ie mineral set command.
