You were close, it's a regulator, two small voltage set resistors, and a capacitor. Again, the reason this particular information is not available (and this is intentional) is because the wiring difficulty is beyond most people's capabilities. If you are capable of doing this relocation and the difficult wiring involved, you can probably figure out what to do without a guide. If we wrote a guide, we would spend most of our time trying to help people who tried it when they were incapable of doing it.
You may be entirely capable of doing the relocation, and since you said this is an extra, go right ahead. I will say the nand is much easier than wifi, just because of how picky wifi is about relocation.
If you wanna relocate the parts, just slice that part off the board and put it somewhere else, since it has the resistors and capacitor all right there.
