PHDM17 rescue disk didn't recognise UEFI hard disk on a new XPS 13 7390 notebook

I received a new XPS 13 7390 notebook and proceed to create an image of the hard disk using bootable PHDM 17.13.1 Rescue USB Media. BIOS is set on UEFI and Secure Boot.

PHDM 17 successfully boot but unfortunately it didn't display any internal hard disk except the rescue USB.

I disabled Secure Boot, same result i.e. no internal hard disk display.

Details of new XPS.

- XPS 13 7390 Bios 1.4.0

- internal hard disk is m.2 PCIe SSD-0/SATA-2 / PC SN520 NVMe WDC 128GB

- Bios does mention Legacy Boot mode is not supported on this platform

I have had no such problem with old XPS 13 which has Legacy boot capability. This is the first time I have encountered with this problem.

Do I need the NVMe driver?

As creating backup image of the original hard disk is key to preserving the notebook as it is delivered New, I am desparate in finding a solution to this.

Any guidance is greatly appreciated.
