Deregister the SLES15 SP1 Module for On Demand EC2 instance.

For one of our On Demand EC2 "r5.large" instance, which is currently hosting SLES15 SP1; we have activated couple of SUSE Modules/Extensions which we are not able to Deregister as the Error says that "SUSEConnect error: SUSE::Connect::UnsupportedOperation: De-registration is disabled for on-demand instances. Use registercloudguest --clean instead."

Please guide us on how we can deregister the same for On Demand EC2 instance.
