Windows Server 2016 - Proxmox 7.3-3 - Impossible to install Virtio Drivers

As the title states, I tried installing virtio drivers from versions virtio-win-0.1.137 to virtio-win-0.1.185, each time on fresh install. They all report the same thing, "windows cannot verify digital signature"...

Which leads me to believe that the virtio drivers were signed with a newer hash that is not supported in Windows Server 2016 without updates. Testing this theory now.

If anyone has some suggestions in the interim please advise.

I found out the problem... if you install the OS with UEFI mode, no virtio drivers are accepted on 2016... for some unknown reason.
I just installed Virtio drivers on 2 x 2016 Server VM's yesterday.
They work as expected.
