I hope I can set the depth to 0 in world

I hope I can set the depth to 0 in minecraft world, and then I can also decide whether to include deepslate on the layer.
because I want to experience mining diamonds without deepslate 12 before, because deepslate is really hard and slows down my speed of finding diamonds.
and if I want deepslate later, I can open map on the normal version and generate deepslate.
