I don't know better secure boot than your own removable media: MBR and
whole /boot on an USB key, and full disk encryption.
If you really need that level of security, don't trust to any installed
boot (UEFI/GRUB/etc).

Mainboard support for UEFIs aren't capable to trust the boot so
transparently as FOSS does.
