Turns out that the Samsung m.2 on this laptop used scsi drivers. I ended up installing Windows 7 then Windows 10. Dual boot success.

For Win 7
Under CSM enable UEFI boot.

More or less like this
OS type Windows UEFI = Secure boot, so if OS type = Other, secure boot is disabled.

for CSM, here are the current settings (in bold)
Launch CSM.......................................(Auto, Enabled, Disabled)
Boot Device Control.............................(UEFI and Legacy OPROM, Legacy OPROM only, UEFI Only)
Boot from Network Devices...................(Ignore, Legacy Only)
Boot from Storage Devices....................(Ignore, Legacy Only, UEFI Driver first)
Boot from PCIe/PCI Expansion Devices....(Legacy Only, UEFI driver first)

Boot from the Win 7 installation disk ON UEFI MODE (important).

Install on the large empty NTFS partition

For the updates MS releases SP2 for Windows 7

Yes, you have to load the m.2 ssd nvme drivers. As you already have added the USB drivers, during installation you can add them from a USB flash disk.
If you want to understand how the drivers affect Win 7 installation disk
Create a Windows 7 USB flash installation with new drives for new MB's
I can't seem to get this working at all, can I msg you privately pleasE?
