6. Create ‘New Policy’ or ‘Edit’ existing policy you have and is applied to the device you want to push this setting
7. Select ‘Default_Inspection_Protocol_Disable’ from left tab and click right-arrow add button to add it to “Selected Prepend FlexConfigs”
8. You can click on magnifying lens button to see the configuration it will push and verify it has ESMTP in the list
9. Click on ‘Policy Assignment’ and add the device from the list you want to deploy this configuration to device.
