Cannot access Security in UEFI to turn off Secure mode

I am trying to enable hibernation. I have the swap disk done, the update grub boot loader, added the sec policy from here. The last thing is to disable secure boot mode in my Aspire 5. I am currently running dual boot and when I access the UEFI menu every option can be configured except for the security tab where secure mode must be disabled.

Could this be a consequence of the dual boot or any other suggestions?

On my Acer, it was in the Boot tab, not security. I have no idea why.
I had to create a Password before it would let me change the setting.

Welcome to the Forum!

Could You post some Pictures of Your BIOS? And have You checked if You have a Reset Option?

That was the problem! Thank you. What a strange way to enforce security....
