SSD fitment in Larkbook X

I just bought a Larkbook X second hand.
I have a bigger capacity and better SSD.
Does it fit to the Larkbook X?
(connection of new SSD was good in another asus laptop with the same factor ssd connection as chuwi ssd has)

Since that, found out it fits BUT laptop doesnt start, its not recognized. Larkbook X official promo says its NVMe compatible tho.
Seen other Chuwi topics saying nvme is not working.

Is there a chance it can work later with a BIOS update, or physically its not possible?

m2 ssd .its not compatible with nvme
