Path reports are limited to "Aggregated" granularity. At the same time, "Page Views" is the only metric available to choose from. This behavior is specific to the Pathing reports in Adobe Report Builder and due to the Report Builder API’s limitation.
As the request is created through the Adobe Report Builder request wizard, the 'Apply Granularity' drop down gets disabled as a path report is selected. The granularity gets set to "Aggregated".
