@Hazel123 There are sites you can probably find unlocked versions of the BIOS for that laptop (HP almost certainly have a password they can use to reveal any hidden BIOS pages/ sections to access hidden options if they exist), but I seriously advise
not trying to flash with one of the custom BIOS files unless/ until you are willing to risk bricking the device, so maybe once you replace it further down the road, if you are willing to experiment with it.
Obviously such sites may host malware disguised as/ integrated into BIOS file images so extreme caution and deep research is a must.
You could also buy a device designed to connect directly to the BIOS chip with software that allows you to edit, export, overwrite and flash the BIOS, again such a device is super easy to use wrongly and brick the system being worked on if used without caution and knowledge. :)
