As the title suggests, I can modify vanilla biome, more precisely, I cannot remove any feature.
The one below is currently my BiomeLoadingEvent in which I am trying to remove all OreFetures from all overworld vanilla biomes.
I've tried a lot of manual iterating, removeIf, but all of them return false when checking for the correct feature.

	@SubscribeEvent
	public static void biomeLoadingRemove(BiomeLoadingEvent event) {
		
		Category category = event.getCategory();
		BiomeGenerationSettingsBuilder genBuilder = event.getGeneration();
		
		if (category == Category.THEEND) {
			
		} else if (category == Category.NETHER) {
			
		} else { 
			for (Decoration stage : GenerationStage.Decoration.values()) {
				genBuilder.getFeatures(stage).removeIf((supplier) -> {
					ConfiguredFeature<?, ?> configuredFeature = supplier.get();
					return configuredFeature.feature() instanceof OreFeature;
				});
			}
		}
		
	}

am I doing something wrong, and if so, what?
thanks for replies

The ConfiguredFeature will most likely contain a DecoratedFeature (which is a feature + its placement).

You should use ConfiguredFeature#getFeatures, which will return a stream of all features in the chain.

thanks, I changed my event like this and it works

				genBuilder.getFeatures(stage).removeIf((supplier) -> {
					ConfiguredFeature<?, ?> configuredFeature = supplier.get();
					for (ConfiguredFeature<?, ?> feature : configuredFeature.getFeatures().collect(Collectors.toList())) {
						if (feature.feature instanceof OreFeature) {
							return true;
						}
					}
					
					return false;
				});
			}
		}
