Unlikely. This type of mosfet is very rare on this PCB.

In addition to SUAH, there is another description, this time generic, GND.

Looks like a piece of exposed silicon caused by plastic coating to chip off. That's why I said it could be a die size BGA.

 :palm:

I thought I made reference to the GND pin that many of these ICs have.
