You just need to add/remove biomes from the tag #minecraft:has_structure/shipwreck
ServerEvents.tags("worldgen/biome", (event) => {
event.get("minecraft:has_structure/shipwreck").removeAll()
event.add("minecraft:has_structure/shipwreck", ["mod:your_biome_here"])
})
this is 1.19+
Oh wow, thanks!! Footer told me it was impossible lol
@uneven jungle 
he might have read it as biome edit, not structure where it spawns which you can do via tags
editing biomes is datapack only
editing tags you can do via datapack or via tag event
Do you know of a way to find the biome id?
