How can we disable portworx encryption in Running cluster?

Can anybody help me with process to disable the encryption in Running cluster

I do not think encryption in Portworx functions this way. Either you can apply encryption at the class level (check the different storage classes that come with the Portworx installation) or at the volume level.

For SC, we use
secure: “true”

For PVC, we use the annotations:
px/secure: “true”

In other words, use non-encryption class or use without annotations for no encryption.
Use ‘kubectl get sc’ to list the different classes.
