may or may not make a difference, but you probably do not need:

<key>Type</key>
                <string>Laptop</string>

Ye I know this, I tried without this one, nothing changes

you could try:
device-id Data 9B3E0000

also test without brightnesskeys.kext

no result, with faked id + brightness key, faked id without brightness key

nothing changes((( Also I cleaning NVRAM after every change.

So, I have tried all ig-platform-id for comet lake with 3 connectors, and wrote right device-id for my CPU that is natively supported by DevIDs, but I have no result with fixing that brightness adjustment.

Also deleted useless connectors patch, because connectors anyway depending on Nvidia GPU, so they were useless, I guess... this one looks more logic
