I used to have that board but with a UFS2.1 version, so I can't really tell. https://github.com/96boards/documentation/blob/master/consumer/hikey/hikey620/hardware-docs/hardware-user-manual.md#storage indicating only a single eMMC device and a SD.
Either way, AFAIK there are no production designs that make use of more than a single embedded flash storage. This goes for both eMMC and UFS.
Thanks, Avri
