I don't fly the 'bus but, if the FDs are providing vertical guidance on the Baro-VNAV path and (pretty accurate) lateral NAV guidance, why wouldn't you leave them on?
Here's the Jeppesen chart. It shows DA(H). This would be considered an RNP AR approach by the FAA, and would be classified as an Approach With Vertical Guidance (APV) as opposed to precision or NPA.
My recollection may be faulty, but I believe the Turkish crew that when into the mud at VNKT was criticized for leaving the FD on below DA.
