BIOS update blocked - F.55 to F.56

[NiveaAJ]

I noticed that I had a very old BIOS (F.38). Surprisingly, none of the HP Tools (support assistant) and websites were able to detect this. I went to the support page for serial number of my product and downloaded the latest BIOS version F.56.

On trying to update, encountered the "BIOS update blocked" greyed out option. Then I went to the version history and it had the F.55 (HP Pavilion - 15-au624tx Software and Driver Details). That update went fine and the current version is F.55

Even after that I'm unable to update the BIOS to F.56. I even updated the UEFI to the latest version from the HP website - 10.8.0.0 but it doesn't have the Firmaware Update option.

How do I update the BIOS to F.56?
