Compare ioreg at PCI0->RP01 tree and you'll see the obvious difference.

Capture ioreg without patch.
Capture ioreg with patch.
Load both.
Arrange Windows side-by-side.
Navigate in both to PCI0->RP01 tree.
Compare with your eyes and brain.

What data to compare, I see the difference, but how do you know that it really turns off the video card?
Do not use the search box!
(you're interested in the difference in hierarchy under RP01, and search is not useful for seeing hierarchy).

For the life of me I can't appropriate _OFF or _ON methods. I've looked into every .dsl manually and by using grep, but the result is nigh.

❯ grep -l Method.*_OFF extracted/*.dsl
zsh: no matches found: Method.*_OFF
I have disabled iGPU and have 1070GTX in first slot and RX560 in second PCIE slot, which I use for macOS. I'd love to disable first card (1070) using SSDT, but I can't find appropriate methods.

Your profile has no laptop hardware details. Please fix as per FAQ:

Because it's not a laptop, I'd like to do it on desktop. I know it's a laptop support form, but I thought I could use similar methods to disable one of my desktop GPUs.
