How can I disable or remove a WORM copy created by the CommServe DR Extend policy?

Hello,

We are using Commvault version 11.24. The Extend policy for CommServe DR is enabled, and it is consuming far more tape media than expected.

The copy is configured as a WORM copy, not a Compliance Lock copy. I cannot disable or delete the WORM copy. I also tried using the AllowUnsetComplianceLockOnDRCopy registry key, but it had no effect.

Is there a supported way to stop the Extend policy from creating or extending this WORM copy, or to remove the copy and reclaim the tapes? Since this is a WORM copy rather than a Compliance Lock copy, should a different setting or procedure be used?

Any guidance for version 11.24 would be appreciated.
