HP Recommended
Product: HP Pavilion 15.6 inch Gaming Laptop PC 15-ec2000 (2P6B3AV)
Operating System: Microsoft Windows 10 (64-bit)

Does anyone know how to flash a modified BIOS to a new HP laptop without file signature validation?

 

I ask because my new laptop does not have CSM Legacy Boot available as an option in the UEFI/BIOS so I have modified a BIOS image so that the feature is enabled, but... However I cannot flash this new modified image because the HP flashing tool requires signature verification.
