Surface Pro 3 and Windows 10 issue

[PortableDave]

I am working on a Windows 10 image for Surface Pro 3 (using SCCM 2012 to build the device) devices. I'm using the latest 7.9 M3 display link corporate tools.

When I login and connect the display link dock the drivers install as expected. On first reboot I am prompted with a bluescreen advising that the digital signature of dlkmdldr.sys could not be verified with error code 0xc0000428. If I turn off secure boot in the bios of the device I can boot again. Obviously we don't want to do this for every device. Any ideas what could be causing this (we don't experience the issue on Windows 8.1). I've attached a screenshot of the issue.

edit: Forgot to mention it's a Toshiba Dynadock U3.0
