Hi
@newbie1998...
First, we have all our settings documented
here and the Group Policy document
here. For Office activation, you don't ever need to enable this setting as it is automatically included when using just the FSLogix profile container and is enabled by default when using profile + ODFC or just ODFC only.
If you are having Office activation issues, you may need to validate your
shared computer activation or open a support case.
HTH 😊 👍🏻
