It comes from the southbridge chip (CXD90061GG) but the line is probably running in one of the layers under the top layer of the PCB.
I don't know any other point where it pops up on the surface or if the trace is on the op or bottom side.

The top layer is probably just a ground plane so you could do some very gently grinding in that area to see if the trace shows up in one of the layers under that ground plane.
Just like a kamikaze mod that is used for connecting the DAT0 line on the Switch (see the Picofly sticky thread for the details).
Putting a small wire through the hole and applying some solder might also do the trick.
