M.3 slot in One Mix 3

[Tomthepim]

I'm struggling to find a definitive answer to this online. But as far as I can tell, the One Mix Yoga 3 has a spare internal M.3 slot, but the Yoga 3s and 3s Platinum do not.
Is this correct?

Thanks

It is M.2, and to confirm, the 3S and 3S Platinum do not have a spare slot.

Yes of course, M.2.
Thanks so much for your quick response.
