Human Factors
We taxied out for takeoff and was notified by the West Ramp Control that ZZZ Operations wanted us to return to the ramp due to a concern with our Dangerous goods on board.After coordination with Ramp Control; we parked and shut down our engines to have ramp personnel access the aft cargo bin. I phoned Dispatch to notify them of our situation and to also request that Load Planning join our conversation. The Load planners brief was that one or both of the DG's were unsecured in the aft bin position 6 and needed to be moved to position 4.Ramp personnel moved and secured DG and said we were ready to depart.  We coordinated with Dispatch; Load Planning and confirmed on board fuel. Checklists were completed and we continued uneventfully.
Air Carrier Captain reported a Dispatch directed ground gate return to correct a Hazmat cargo load configuration error. Ramp personnel corrected configuration error and flight continued to destination with no further issues.
