We have signed a driver with MS partner center EV SHA-2 on October 2020, today August 2021 the driver though installed is not mounted during boot, only once secure boot is disabled in BIOS.

How should we address this issue?

    Thanks, but I think that this option disables signature testing. It is a production delivery, not a testing set.
