As I understand, as of 2021, drivers that run in kernal mode will need to be signed by microsoft by submitting test results to the hardware program. What if I just want to sign a "driver package" ie. inf/cat file that references an already signed kernal mode windows driver such as usbser.sys? Microsoft documentation doesnt seem to cover this case.
I am hoping to sign cat file with a standard code signing certificate purchased from a CA after the Microsoft Root Trust Program no longer supports signing certificates with kernal mode signing capabilities.
