Hiding all icons

We are using Inteset on a Windows 10 1709 build. The Start menu is working correctly, only displaying the icons pinned to it and nothing else. Most of the task bar is also missing. However, on the right side of the task bar there are icons available for things like: Power, network, Bluetooth devices, Sync center, Vipre, etc. Some of the icons are not accessible though visible. Some of them are available.

Is there a way to hide these as well?

Thanks!

All Taskbar icons can be removed by going to Windows Settings > Personalize > Taskbar > Notification Area > Select whitch icons appear in the Taskbar

Thank you for the reply. I did end up having to go a step further and use Group Policy to hide the notification box.
