Office 2016 - Your Privacy Option Popup

Hi

Globally we are using local Office 2016 Enterprise. I would like to do Uncheck/grey-out the option "turn on optional connected experiences." See visual below. 

From my search this can only be done by GPO. Option 1 below. 

This can also be configured in the Office2016 / 2019 / 365 ADMX Group Policy files.
User > Policies > Admin Templates > Microsoft Office 2016 > Privacy > Trust Centre

1. Allow the use of additional optional connected experiences in Office
2. Allow the use of connected experiences in Office
3. Allow the use of connected experiences in Office that analyze Content
