Hi Grr, It is not a simple challenge even using a microcontroller running a baremetal busy loop code, let alone using a RTOS. More info:
https://forum.allaboutcircuits.com/threads/programming-a-1-ns-delay-for-microcontroller-processor.90227/ It is better to have a dedicated hw taking care of the ns-resolution delays and using the RTOS to control and gather the resulted data. What are trying to achive? (of course if can share or talk about it).
