Usage: vault policy delete [options] NAME

  Deletes the policy named NAME in the Vault server. Once the policy is deleted,
  all tokens associated with the policy are affected immediately.

  Delete the policy named "my-policy":

      $ vault policy delete my-policy

  Note that it is not possible to delete the "default" or "root" policies.
  These are built-in policies.
