Maps How do I disable mod spawns?

[Quackinton]

I would like to build a golf course (just for fun), and I want there to be no mobs spawning, how do I prevent them from spawning (I know you can disable mob spawns in journey mode but you have to do it manually when you join the world, if that’s the only solution then it’s totally ok) I was planning on creating a new world and not using an existing one. Also another question, would Tedit be good for building the course?

Enemy mob spawning is entirely disabled on Classic worlds (and for a golf map, who needs Expert/Master mode stuff?) around towns with at least three NPCs. Peace Candles and Sunflowers can be placed to reduce spawn rates. Nothing will spawn in front of player-owned background walls, so you could put everything in front of glass walls.
