Why each option
UEFI secure boot in vSphere requires EFI firmware on the VM, Virtual Hardware version 13 or later, and a guest OS that natively supports UEFI secure boot.
UEFI secure boot is a feature of the EFI firmware standard and requires the VM to be configured with EFI firmware, not legacy BIOS, to enable cryptographic boot validation.
Virtual Hardware version 12 does not include UEFI secure boot support; the feature requires Virtual Hardware version 13 or later.
Legacy BIOS firmware does not implement the UEFI specification and therefore cannot support secure boot, making BIOS firmware an invalid prerequisite.
Virtual Hardware version 13, introduced with vSphere 6.5, is the minimum hardware version that exposes UEFI secure boot support to the virtual machine.
The guest operating system must support and participate in UEFI secure boot by validating its bootloader and kernel modules against the secure boot certificate database embedded in the firmware.
