Zapp's Invasions Utilities
The author built this one for Minecraft 1.21.1 on NeoForge. On other versions it may install and then do nothing.
This mod add on Block which reduces spawn rates of monster by 99% in your needed distance. It can only placed once per dimension.
How it works:

• 8 Blocks around the Protector:
This is the defending area. Invaders will spawn and try to destroy your Protector if you running out of capacity.
No blocks can be placed in this area!
• 8 to ∞ Blocks around the Protector (default = 100 Blocks):
In this area, the protector reduces spawn rates of monsters by 99%. Each prevented spawning needs fuel / capacity.
Remember The larger the protected area, the higher the fuel consumption.
Zombie Invaders Attacking the Protector:

The Protector is destroyed:
(The world is corrupted until a new protector is placed.) Now you can't place anything but crafting tables and the new protector in this corrupted world.)
! Pro Tip: You can go to other dimensions these are not corrupted.
