Disable driver signature enforcement remotely

Hi,

I'm getting error "the third party INF does not contain digital signature information" on a virtual machine on Microsoft Azure. I need to go to advanced boot option menu which is not possible through rdp connecton. I have even tried two commands:

1. bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS
2. bcdedit -set TESTSIGNING ON

Reboot and tried to install the software. The error is still there.

 How can I disable driver signature enforcement remotely.
