I want to install windows 11 on HP Elitebook 820 G2

Hello, I wanted to install windows 11 on my HP ELITEBOOK 820 G2. But it says "This PC can't run windows 11 because it does not support secure boot". I tried to enable secure boot from the bios menu but I can't enable it, because the option is blank. My Bios version is 1.31. Here are some screenshots regarding my problem. Please have a look.

Hi:

You cannot turn on secure boot when W10 is installed in Legacy mode.

You would have to reinstall W10 in EFI mode.

Then you would be able to turn on Secure boot.

To install W10 in EFI mode, you boot the W10 installation media from one of the EFI boot devices listed in the F9 boot options menu.  There should be an EFI DVD and an EFI USB flash drive.

Your PC is still going to fail the health check because the processor and TPM don't meet the currently established standards to install W11...

I installed windows 11 from an iso file, I had to make some changes so that it can run on my PC. But even after installing windows 11 PC health check  still says I am ineligible to run windows 11. Will there be a problem if I keep using it anyway? It would be a great help if you answer my question.
