Welcome to the Community Forums.
On 720 machines that came in with M.2 NVME SSD, it have a SSD bracket assembly (part number 01EF905 - M.2 SSD Brkt Assy 213mm MB) that would allow it to screw in to secure the SSD as shown in the image below.
Others folks just taped it with an electrical tape with strong adhesive as a DIY alternative for the moment
Hope this helps answer your query.
