Is there still no way to remove underwater blue fog? I want it to be scary under the sea, not bright enough that I can "skyline" structures and mobs with perfect vision

You can do that with this link, in a way
https://misode.github.io/customized/?tab=biomes
Just replace all the biomes you don't want in your world with ones you do want, so if you never want to see ice spike biomes just replace them with jungles. Never want deserts in your world again? Replace them with basalt deltas, this is how I created a badlands and desert only world by replacing everything mountainous/plateau like biome with mesas and everything else with desert. I even removed all the rivers and oceans, replacing them with desert biomes and lowering the worlds sea level to -63
You have to start creating a new world and then place the datapack from the link you make into the datapack folder and start the world anew
