for this you will have to deep dive in UI builder and see which component renders that and then make changes to the duplicated version of that.

If my response helped please mark it correct and close the thread so that it benefits future readers.

Is it a UI action? if yes, you can add "UI visibility" under the UI action related list.

Hi,

It is not a UI action. 

@Rachna S 

Go to sys_ui_action table and disable it based on your requirements

If this helped to answer your query, please mark it helpful & accept the solution.
