Turn off the doMobSpawning gamerule to prevent mobs spawning naturally:

/gamerule doMobSpawning false

You will need to have cheats enabled to run the above command. If you have not, you can temporarily enable them by the following:

1. Open the menu while on the world (ESC)
2. Press Open to LAN
3. Switch Allow Cheats to ON, then press Start LAN World
