Help disabling ore generation from a mod 1.20.1

Hey, I'm trying to make a modpack for me and my friends. However one of the mods called Palladium has some extremely useless ores, so I wanna stop them from generating at all to reduce bloat in the pack.
I've done a lot of configs editing and some kubejs editing in the past. However I'm really green when it comes to datapacks. 
I've been doing my best to read up on how to do it, my best bet so far was setting up the folder structure like: Disabling palladium orespawn\data\palladium\worldgen\configured_feature and Disabling palladium orespawn\data\palladium\worldgen\placed_feature
Using {
  "type": "minecraft:no_op"
}
in the configured_feature folder files and using:
{
  "type": "minecraft:random_selector",
  "config": {
    "features": [],
    "default": {
      "type": "minecraft:no_op"
    }
  }
}
in the placed_feature folder files. Using the same ore_lead names for the json files as the mod itself uses in its data file. 
Though when I attempt to add the datapack to my world, I get "failed to validate datapack" so I'm obviously doing something wrong. 
So I'm wondering if anyone could please help me get this working, I feel like it should be a pretty small/simple datapack but I can't tell what would be right or wrong. And if you have the time and energy to do so, if you know a quick fix and could just write up the datapack quickly and send it to me then I'd be forever grateful. Thank you for reading, some more info:
