Deactivating or disabling a specific axis using HAL

Hello,I would like to inquire about the possibility of deactivating or disabling a specific axis using HAL commands. Specifically, I am attempting to prevent the stepping signal to the X-axis. I have attempted the following command without success. 

unlinkp hm2_7i96s.0.stepgen.00.velocity-cmd

How can I deactivate an axis using Hal command?

Thanks

Yes, that would cause a following error...

A cheap trick that will stop motion but not cause an error
would be to set the step time very short:

hm2_7i96s.0.stepgen.00.steplen 10

Thank you very much
