No there no way to restrain symmetry axes using Chimera map fitting. You can optimize rotations only preventing any translation, but full rotations will be allowed.
You could use the Chimera “measure correlation” command with the rotationAxis and angleRange and plot options to measure the correlation value as one map is rotated relative to the other. This doesn’t report the maximum correlation position but you could find the maximum in the tabulated values in the reply log.
