The Z Turbo Drive g2 has an NVME controller, instead of the typical sata/ahci controller used by most other SSDs. I suspect you may need to update your system. Make sure the BIOS is at rev 2.14 and all other drivers, including USB are updated.
I recommend the use of HP SDM (Softpaq Download manager - www.hp.com/go/sdm) to update the system. When it runs and downloads the latest catalog,
* select 'check for updates' - if not the default when you run SDM
* install auto-checkmarked drivers, NOT the BIOS, at this point
* install any other (ONLY) drivers + Essential System Updates softpaq
* select BIOS update (if needed) and download, then on the downloaded line in the bottom window, right-click the entry and select Install
* Reboot
