I did not, but of course you can. Either by using an adapter (maybe a printable one?), or – if it is an SSD – by just placing the drive there and hld it in place with one screw.
If there already is a drive installed you want to removed and there is no spare cover, you can also print one.
(You can of course buy the parts instead of printing them. Those adapters and covers are fully standardized and widely available.)
Nein, nein, nein!
