Turning off head tracking

Is there a way to turn off head tracking but retain the stylus tracking?
I know that if I do not call zcUpdate, head tracking will be turned off. However, this will disable my stylus tracking too.

Then I tried the following:
zcGetTargetByType (g_zSpaceContext, ZC_TARGET_TYPE_HEAD, 0, &g_headHandle);
zcSetTrackerDeviceEnabled (g_headHandle, false);

But this does not disable head tracking too. Is there anything I have done wrong?

I’m unsure why disabling head tracking doesn’t work. The easy alternative should be to stop asking for updated camera poses when you desire no tracking.
