In 1.19 there was no config option to turn off teleporting into other dimensions, and this is still problem in 1.20.1

[teleporting]
#Determines the range that a player can be teleported from their current location
#Range: > 1
teleport_range = 400
#Determines the chance a player will be teleported
#Range: 1 ~ 100
teleport_chance = 1
#A list of Dimensions that angels cannot teleport players to
banned_dimensions = ["minecraft:the_end"]

Added it for the next 1.20 version
