Thank you to Ester Park from the University of California in San Diego who demonstrated using a National Instruments myRio that the Microsoft Hololens API of the Haro3D library is compatible with LabVIEW Real-Time.
The apparent delay between the commands and responses of the motor is caused by the lag in the Hololens video recording.
It is therefore possible to control a National Instruments real-time device directly with a Hololens.
