FLUID Delegate Preferred Phone Number in Manager Self Service

We are currently working to apply HCM PUMs 37 through 39 and are activating the introduced FLUID pages. Our client is concerned about being able to see Delegates Preferred phone number in Manager Self Service because this number could be a private number such as cell or home phone.

Is there a way to configure a default to always show work number instead of preferred number?

Thank you!
