Dimension Doors Config for Rifts

[Sapphire_Digger]

Hello! I was wondering how to turn off rift spreading in the config. Everywhere I look shows a different config from what I have currently, and I'm getting frustrated at the lack of direct answers for this. Any help would be appreciated, thanks!

Here is the config I have currently:

# Configuration file

dungeons {
    # Min: 5
    # Max: 2147483647
    I:maxDungeonDepth=50
}
