How to make Overworld-like dimension NOT spawn ores

Hi, i'm making experiments for my upcoming mod for a whole new dimension and i want the generator to be based on my biome base stuff (so i have to pick Overworld type) and the generator makes some unnecessary stuff, like it generates trees even though i set the tree generation to 0 in the biome settings, it also generates default ores and caves which i don't want to happen. Is there a solution or do I have to wait for the next MCreator update? Thanks.
