Windows – secure boot can’t be selected in BIOS in Windows 10 home edition

biosoemuefiwindowswindows 10

I need to turn off the secure boot for a project however when I use "recovery option" to change the startup setting
enter image description here
however after restart when I go to "SECURTY" tab, I only can use the arrow keys to move between Administrator Password and Delete All Secure Boot Variables and it jumps of the "System Mode" and "Secure Boot" in between (they are not deactivated it seems but can't be selected). In the "Main" tab it shows that access level is administrator. Please suggest fixes to this issue.

The laptop brand is GIGABYTE P57 which is a gaming laptop.

I also set the administrative password, saved the BIOS setting and got back to it and still can't hover over the "Secure Boot" option.

For those who might suggest, there's no notion of secure boot in the P57 manual:
