Driver Signing
Your DisplayLink driver is unsigned. It won't work with 64bit Windows OS. I suggest fixing that if you want people to buy your product.
Our drivers are signed. If you use Windows 7, update with Microsoft security patches to verify Microsoft digital signature successfully.

Windows Defender objects and disallows installation of your WIndows 10 driver because it is not digitally signed.

dlidusbx64 is not a Windows 7 driver, and will not work on it. That is a class of driver for Windows 10 Anniversary Update onwards only and therefore will never be WHCP certified for Windows 7 because that category of driver doesn't exist on that OS. This is why Windows 7 cannot verify its WHCP signature.
I recommend you use the appropriate "DisplayLink_Win7-10TH2.msi" MSI corporate deployment packages for remote deployment to Windows 7.

I should probably also mention the workstation is Windows 7 64bit

I downloaded the latest drivers (DisplayLink USB Graphics Software for Windows 8.4 M0.exe) you have on your site for Dynadock. I'm deploying with SCCM so need to open this up as it won't install quietly. One of the drivers in there (dlidusbx64) reports as unsigned. The workstation I am deploying to is completely up to date with MS updates.
