Hi,
Unable to view the screenshot that you posted but if it is about the new app notification etc, you can do with client agent settings and also the deployment user experience notification settings.
Client Settings: Computer Agent\Show notifications for new deployments = "False".
You can also configure the User Experience\User Notifications configuration setting for the app deployment to "Display in Software Center, and only show notifications for computer restarts".
