Maybe!
That is called air balancing.
You could have one take off that has a poor location. For example too many other take offs in the area or by a transition in the ductwork.
Try reducing flow gradually to some of the other diffusers or registers and see if the volume picks up to the problem zone.
You might be able to speed up the supply fan and then choke the flow to some of the other takeoffs. It really is tough to say without seeing the system. Is this particular room at the beginning or the end of the run?
To the original poster, I have seen in one case where someone stuffed the duct with course stainless steel wool to reduce flow and noise when the balancing damper was not accessible. Problem was that after a period of time it loads up with dust as it acts as a filter. It actually did work quite well though....
