Hello, here is finished your mod with removed whitelist
https://www.bios-mods.com/BIOS/index.php...miloml.exe
However, this bios is external RSA signed and not enough patched, i think.
Flash it at your own risk, you need prepare recovery USB stick if mod is failed.

Even after unlocking all option in BIOS video switch isn't working.
Whatever you choose result is the same.

I see,but never tested,some hardware mod that disable ATI video card,but that is just in case of damaged ATI card.

Other way to start with IntelHD only is to power notebook on battery only.That way BIOS itself disable ATI video to save power.

As for your problem,I don't know if that is possible.
Signal path for LCD display is:
Intel HD to MUX IC
ATI video to (same) MUX IC
From MUX IC to display.

That MUX IC is controlled by EC and as result in some situations connect display to ATI or IntelHD.

In your case you try to use something like muxless design of some notebooks.
But I think only adding hardware is not enough.
