How to prevent structures from spawning.

Hi, i am fairly new to running a minecraft server and i am still in the setup.
I use chunky to pregenerate the world.
And i wonder if it is possible to prevent structures from being generated.
The structures i want removed are Villages, End Fortresses, Ruined Nether Portals, Sea Temples, the deep dark and dungeons with mob spawners.
What would be the most elegant way to achieve this?
