This can be done directly on the system by updating the Authz policy file and waiting at least 10 seconds for OpenConfig to reload the changes:\n\nswitch#bash timeout 100 echo \"{\\\"name\\\":\\\"block gNOI TransferToRemote policy\\\",\\\"allow_rules\\\":[{\\\"name\\\":\\\"allow_all\\\"}],\\\"deny_rules\\\":[{\\\"name\\\":\\\"no-one-can-use-gnoi-transfer-to-remote\\\",\\\"request\\\":{\\\"paths\\\":[\\\"/gnoi.file.File/TransferToRemote\\\"]}}]}\" | sudo tee /persist/sys/gnsi/authz/policy.json \u0026\u0026 sleep 11\n\n\n\u00a0\n\nThis will cause attempts to run the TransferToRemote RPC to fail with a \u201cPermissionDenied\u201d error code."
