Windows 10 Edge Pinned on Taskbar

Is there an easy way to unpin Edge from the taskbar in windows 10 (1703)? Every time a user unpins and reboots it comes back. I have tried using the start.xml file with <CustomTaskbarLayoutCollection PinListPlacement="Replace"> but I cannot seem to get this working. Just wondering if anyone had a way to do it with AppSense 10.1 FR3.

Thanks
