If there is a necessity to always hide an item in a Identity Management template and there is no suitable directive for that, you can use an approach by setting a condition that will never match, for example by using a nonexistent condition. The preferred or recommended option is to remove/comment the code out completely.
For example:
showIfDisplayMode="conditionThatNeverMatch"
The condition can be added to a span or div container of the item you need to hide.
This solution can be applied when an item should exist in a template but should be not visible to users.
