Secure Boot not found in BIOS?

I installed Ubuntu on my laptop yesterday and now I get the message w-lan network adapter not found. Since I have already read a little, many write that one should deactivate the Secure Boot. Unfortunately, I don't find that in my BIOS. Could it be that it has another name?

Phoenix BIOS version A10

I think Secure Boot is only available with a UEFI BIOS.
