My problem is: if I call https://graph.microsoft.com/v1.0/sites/{site-id}/drives/{drive-id}/root/children all I get are the top-level items of that drive.
How can I achieve to get all the subfolders and files of the drive?

There's no endpoint to get all items in a drive with every file from every subfolder at once.
Below endpoint maps to a test library MyDoc3.
/sites/siteid/drives/{drive-id}
Then, below endpoint use to get children of FolderA in MyDoc3.
/sites/siteid/drives/{drive-id}/root:/FolderA:/children
