Do holograms also cause  vergence-accomodation disparity?
No. As I pointed out in the piece, there are a few 3-D displays -- holograms, moving-mirrors, and volumetric among them -- that do not cause vergence-accommodation disparity. Holograms reconstruct the wavefronts that were present at the time of the image capture, presenting both accommodation and vergence where they would have been to an observer. 



REAL holograms behave like that. There are pseudo-holograms, incluing most 
computer
generated ones, that do not.

A first rate monochrome hologram, properly illuminated by a laser,
is a thing of amazing beauty and realism.
