Need to disable secure boot without 4 digit confirmation

HP Recommended
Microsoft Windows 10 (64-bit)

I'm trying to remotely deploy OS using WDS PXE Boot. The PXE deployment works only when secure boot is disabled. For the PXE boot to work in EFI mode, I am disabling Secure Boot remotely using HP BiosConfigUtility and restarting the client (cannot use legacy mode for PXE). But the client then asks me to input a 4-digit verification code during startup. For my project need, I cannot press anything on the client system for OS deployment. What is the way to disable the 4-digit verification? If not, then how to disable secure boot without the need to be asked for 4-digit verification on next startup?
