Before i throw out input or ideas, was wondering if you planned on running windows OS 7 and above on the laptop ?
Its a very nice laptop and should have shiped with win10, alongside a 4k/UHD IPS display.
Anyways i had to double check before shooting myself with info off the top of my head becuase its become almost a daily routine for me to boot up and start thinking about all the new security (measures) <----- want that word to stick out for the listed below info
Your short answer:
Intel BootGuard is something that they wanted to be Equal to and Better than TPM.
Boot Guard has two separate modes, according to Intel. Every single PC OEM we know of configures it to work in “Verified Boot” mode. The PC manufacturer fuses their public key into the hardware itself. If the UEFI firmware isn’t signed by the OEM—that is, created by the OEM—the computer will halt and refuse to boot. That’s why you can’t modify the UEFI firmware or change it to something else.
The longer answer:
There’s also a second option: “Measured Boot” mode, where the hardware securely stores information about the boot process in a trusted platform module (TPM) or Intel Platform Trust Technology (PTT). The operating system could then examine this information, and—if there was a problem—present an error to the user.
TPM and PTT both are fully hard baked into windows10, to do what your trying to do you would have to completly remove these component support modules rendering the entire OS unusable.
You can try running the most free of free open source OS and you still wont be 'free'
The hardware was manufactured to do exactly what your seeing, no matter how you turn the laptop On.
Unavoidable. I would start looking into first in this order.
Windows HELLO
Biometrics (IR)
TPP
TPM
Secure Boot
Then tag the searchs with BootGuard or Intel and how windows10 is in fact keeping you safe not only online, but through Gaming. Yes, this crap now is gaming related to prevent... Cheating.
Its all in the research and webinaires, hope this helps. There is no GL for this, you purchased Hardware your not performing something like Hackintosh on,
Its a very nice laptop for these reasons.
