Display Name Personalization

Hello experts,

we have this following requirement for the Display Name:

1. Public information about the employee (Directory, Spotlight, Connections, etc.) should be preferred names. Anywhere that the employees or HR/LM from outside of their AoR can access the display should be preferred names. But the HR or LM with the appropriate AoR/direct line or technical management access (My Team, My Client Group searches, Notifications, etc) should see the staff’s Legal Names.

Is this possible? We thought that display name is the name that appears in the user interface or on various screens throughout Oracle Fusion HCM and is not depending on the roles or AOR.
