If not then what's the best M.2 based option so that I can use 5ghz.

You need to consult with your laptop manufacturer for compatibility.

The Centrino Wireless cards plug into the first generation mini-PCIe connector, which is also referred to as the M.1 connector.

The AX200 and AC9560 Wireless cards plug into the second generation mini-PCIe connector, which is also known as the M.2 connector.

Bottom line, No, you cannot use either of these cards.

Sorry,
