How to hide role delegation from the Roles and Delegations screen

We would like to enable to the Roles and Delegations part of the screen from our managers. Currently the only way to set a vacation rule is to go to the Worklist and set Preferences.

How can we hide this part of the screen - I cannot find anywhere in HCM Design Studio to do this nor can I edit any of the components using screen composer.
