Sorry to hear that you are having problems ... and I would like to help you.
If your bios version is older than F.25 Rev.A
(1) Update BIOS
HP Notebook System BIOS Update (AMD Processors)
|F.25 Rev.A||11.6 MB||Oct 21, 2021||Download|
Why should you install the update ?
Updating the BIOS is recommended as standard maintenance of the computer. It can also help resolve the following issues:
- An available BIOS update resolves a specific issue or improves computer performance.
- The current BIOS does not support a hardware component or a Windows upgrade.
- HP Support recommends installing a specific BIOS update.
(3) Enter BIOS > Advanced > Secure Boot Configuration > Legacy Support Enable and Secure Boot Disable
(4) If (3) is not present in BIOS:
Send picture of F9 Boot Device Options menu
Start notebook ... ESC ... F9 Boot Device Options

This could very well be my solution!
Except for one thing: F10 isn't working to get into the BIOS anymore.
The update has been installed succesfully.
When I boot up my computer, if I hold down F10, it just continues to Windows as usual.
No delays, no pauses, no nothing.

(1) Turn off the computer and wait five seconds
(2) Turn on the computer, and then immediately press the [ESC] key repeatedly until the Startup Menu opens
(3) Press [F10] to open the BIOS Setup Utility

So I cannot see legacy options on your pictures, you are right...
(1) Disable USB charging ( when computer powered off )
(2) Disable Secure boot is ok
(3) Take USB flash drive and create a bootable Linux Ubuntu system:
(4) Start your computer, constantly press and release ESC key, then choose F9 boot menu to boot from usb flash drive
(5) Does this work ?
