"The vault lease revoke command is used to revoke a lease/secret created by a Vault secrets engine. Each lease that is created is tracked using a unique lease ID, which can be used to renew or revoke a lease.

You can revoke an individual lease using the command vault lease revoke

You can also revoke ALL leases from a secrets engine using the -prefix flag, such as vault lease revoke -prefix azure/
