don't update dipoles in a rigid body

Dear lammps users and developers:
I use atom_style hybrid molecular sphere dipole
I use fix rigid/nve to define rigid bodys,and there are two atom types in a rigid body.
When rigid body rotates, the dipole of atoms also update which is not what I want. I need to keep the dipole unchanged during whole simulation.
How can I solve this problems? Can you give me some advice?

Thank you in advance!

that is a rather unusual request. i don’t see how this can be implemented without changing the source code.
