No. Apple MacBook's do not support M.2 SSD's, but unfortunately use their own interface. OWC offers SSDs with this special interface especially for MacBooks. However, there do not seem to be any corresponding products for the MacBook Air Mid 2011 in the Digitec range.
There is no clone software included. But there are enough tools on the internet that you could use, for example:

Hi Daneras. You must have misunderstood something completely. M.2 is only the interface, nothing more... Just like SATA. The others you mean are connected via PCIe (NVMe). And your number 2280 is the dimension of the SSD itself (22mm width x 80mm length).
If you want faster ones, you have to go for the Samsung 960 EVO or Pro, for example.
Kind regards,
