How to lock the factory Programming mode on HP

DESKTOP HP PAVILION ALL IN ONE is blocked due to the "factory programming mode being unlocked" after a Windows 10 update: unable to access the BIOS AND WINDOWS 10; THE DISK IS INTACT. IF we lock the factory programming mode of this HP from 2018/2019 everything will work again BUT HOW? There have been several repair attempts by experts but it does not work.
Thank you

Hello anyway.
Thank you for not shouting. Writing in capital letters means shouting.
Several attempts to repair by experts have not succeeded, do you have the option to show the device to an authorized HP service or to contact them? They sometimes have adapted Windows versions for their own software.
Thank you for your response: I contacted HP support and then took it to an "HP expert" workshop, but they have no solution. According to a response from an American forum, users can contact the factory in the USA; previously, HP provided firmware for this issue (special firmware ending in .bin; since 2019? they no longer provide it) and it's impossible to go to CHINA....
Hello,
HP has indeed not provided the SMC.bin files since 2019, and they were only available during the first 5 years of the PC's lifespan.
These were, with proof of purchase, customized files that included the serial number and the hardware identifier of the computer (UUID): it is therefore not possible to obtain one through a third party.
There would be an alternative by flashing the BIOS, but this is only within the reach of trained and knowledgeable programmers familiar with the hardware, I quote:
For trained professionals. This involves desoldering the BIOS chip, dumping its memory area, modifying it with the correct information, then reflashing it onto the chip and finally resoldering it back in place
Hello,
Given the failure of HP's experts, one would have to assume that there are mega-experts on CCM, capable of surpassing the initial ones, who have given up.
There may be some, but that goes beyond the scope of online mutual aid, and nothing says that it wouldn't happen again during periodic updates.
Furthermore, programming chips that support the BIOS requires, on one hand, expertise as a developer in assembly language, and on the other hand, a disregard for the manufacturer's copyright over its components.
However, CCM appears to some, in my opinion erroneously, as the last and infallible recourse when the manufacturer fails.
Hello,
Certainly, but HP doesn't want to hear about it because they no longer distribute the famous SMC.bin.
Indeed, if it's possible, it would require some high-level tinkering by programmers with physical access to the machine, which goes beyond the scope of a forum, even if it were frequented by the Wizard of Oz and, by the greatest of coincidences, by a trained HP technician who has acquired these skills.
