I have seen many similar threads here, but I couldn't find one for my motherboard.
This is the setup I had recommended here, but the alert pops out as seen in the title.

M.2 definitely offers more speeds and yea populated m.2 ports results in disabled sata ports. It is due to limitations of the mobo chipset. Dont worry about it.
