A small hint on that side:
You can disable and force these stuff like the "Windows Defender messages, Action Center, Notification Tray Messages etc pp" to stay away by changing the settings with the "Group Policy editor" ...
Please use this at your own Risk!
This a windows 10 tool, with common scripts collected under a "control panel" like...
To fire up the Group Policies Editor simply type in your w10 search "edit group policy":
To disable or remove the notifications and action center simply follow the following route shown on the screenshot. This will not remove the "balloon tips" or Tray Notifications. These can be found also either in the User Config or Computer Config.
Its worth the time to crawl trough the lists to get a clue about what can be configured and disabled... especially for "playout machines"
