there is a vanilla command that will do this but it comes at a price.
/gamerule mobGriefing false
This command will cause ALL mob griefing to stop.
- Creeper explosions scarring the land
- Enderman picking up blocks
- Ghast fireballs destroying blocks (causing fires?)
- Wither destroying blocks
This command is a op only, run once command. Just set it and forget it.
All of the above changes are only to environment griefing. Player damage still occurs.
Have fun and explore some of the other changeable /gamerule(s)
