I just downloaded that installer and created a VM with an NVMe hard drive. The booted OS found it as /dev/nvme0n1.
I also changed the virtual hard drive type to SATA, and the disk was found as /dev/sda.
I wonder if your distribution has support for the virtual SCSI controller that the tech preview would provide?
I would suggest changing your hard disk type to NVMe (preferred) or SATA and see if you can partition it.
