I've now gone through all the nodes (even unconnected ones) where any kind of input source was possible and set them to internal mic one after another, put on a boot override and rebooted every time. Some pins have white noise, others nothing at all.
If this helps, on the side of Windows, device manager reports there to be an "Intel Smart Sound Technology" device on which the "Realtek High Definition Audio" device and the "Microphone Array" are located.
I think this means, that the microphone isn't connected to the Realtek codec at all, but directly to the mysterious "Intel Smart Sound Technology" device. Even the Realtek HD Audio Manager sees only the external microphone jack and doesn't know about the internal one.
