Looks like the upper M.2 can be routed using some switches to either the CPU or the PCH depending on the CPU used, But the image is too bad to look for the trace coming from the CPU. On gigabyte boards they just disabled the slot for future use. Regardless this socket is just too small for the motherboard to be proportional, just like a weak engine to a big powerfull car. very power hungry but weak and too small sized cpu and I would like too see tghe PCH gone the way of the dodo, that way there will be no need to worry about combining H410 with 10900K, the CPU would come with the PCH integrated and all the drama about hey there is a new chipset every year. I imagine socket 1700 would be a perfect fit for a board that size. I wouldnt pay 299$ for this unless it supported all the CPUs all the way until 1.4nm, which it cannot do obviously, DDR5 will obsolete everything overnight, just becomes outdated for no good reason. And I would be stuck with some Rocket lake power hog beastie for 10 years or worse. 10900F, that would not even have a dedicated M.2 slot.
