It may indeed be that the onboard audio is disabled in the firmware
However that is quite a separate issue from

so I can access UFEL Configuration

which I presume means UEFI - Unified extensible firmware interface

You do not need to resolve the sound problem to enter the UEFI setup

• Navigate to settings. ...

• Select Update & security.

• Select Recovery from the left menu.

• Click Restart Now under Advanced startup. ...

• Click Troubleshoot.

• Click Advanced options.

• Select UEFI Firmware Settings.

• Click Restart.

When you get into UEFI setup
you MAY find it is under

1. Navigate to the Advanced tab.
2. Select built in device.
3. Check the Audio box.
4. Save the changes and exit.

What is the make and full model of the windows 10 probook
I presume it is HP but please confirm make and FULL model
