Secure boot appears enabled in kernel log but not with mokutil

[Aitor Fraile Azcue <aitorfraile@mykolab.com>]

Hi,

I have a Intel NUC DE3815TYBE system and I have updated it without
problems from Stretch to Buster (thanks to the developers!).

To activate Secure Boot[1], I have followed these steps[2]:

 * Confirm that shim-signed, grub-efi-amd64-signed and
   linux-image-4.19.0-5-amd64 packages are intalled
 * Reboot and enable Secure Boot (Standar mode) in BIOS
 * Reboot and check if Secure Boot is enabled

In the kernel log appears as enabled:

 [...]
 kernel: secureboot: Secure boot enabled
 kernel: Kernel is locked down from EFI secure boot; see
 https://wiki.debian.org/SecureBoot
 [...]

But mokutil says there's no support for Secure Boot:

 # mokutil --sb-state
 This system doesn't support Secure Boot

Also with bootctl:

 # bootctl status | grep -i 'secure boot'
 Secure Boot: disabled

I would like to know if I have enabled Secure Boot correctly or if I
have made a mistake. 

Thank you in advance.
