Can not enable Legacy Boot in BIOS

HP Recommended
Prodesk 400 G4 SFF
Microsoft Windows 10 (64-bit)

Hi there.


I have carefully read many threads here concerning similar issues - but I am stuck with the following situation:


On my HP Prodesk 400 G4 SFF I am constantly trying to Enable Legacy boot and Disable Secure boot. No matter what I do, it just doesn´t save the settings.


I have the latest BIOS: 02.22 Rev.A. I even tried downgrading but without success.


I also activated an Administrator-Password as recommended in other posts.


I always go to secure boot options and select "enable legacy and disable UEFI boot" in the drop down-menu - then I save it by pressing F10 (also tried saving by going back to main menu) --- and then reboot.


But then nothing changes!


Is there something wrong with my PC? Will there be a BIOS-Update? Is there any way I can make the BIOS work as it should be?


Thank you!
