Hi:

See if this solution is of help to you...

https://h30434.www3.hp.com/t5/Notebook-Operating-System-and-Recovery/Can-t-enable-secure-boot-in-bio...

Check your BIOS mode in the system information window.

To do that, go to the W10 programs list>Windows administrative tools>system information.

A window will open and you will see a list of stuff.

About halfway down the list, you will see a BIOS Mode line. 

If it indicates Legacy, you will have to reinstall W10 in EFI mode.

In order to enable secure boot, that line has to indicate UEFI.

To install W10 in EFI mode, you would have to boot a W10 installation flash drive from one of the EFI boot sources listed in the F9 boot options menu (EFI USB or EFI DVD).

I have seen seen that post befor  and try every solution  there,

I check bios mode now

it is uefi mode but still have that problem.

is that possible that something in advance option cause this problem?

I try to access advance option in bios but I couldn't 

I don't now how

You're very welcome. 

Unfortunately, I don't know why you can't enable secure boot if the BIOS is in UEFI mode 

I don't have any other suggestions for you to try.
