Delete player spawns

I would like to have a mod for Extinction that removes all default player spawns except for the one in the middle of the Sanctuary. I desire a more adventurous experience where everyone on my server must venture to the areas of the map they wish to live and make a bed to respawn there, rather then being able to spawn all over the map. If someone could make this mod or tell me how to, that would be much appreciated.
thank you,
