    Let see if I understood correctly:
    - The laptop has only a M.2 slot and it works only with M.2 SATA SSDs, but doesn't with M.2 NVMe SSDs.
    - There is no 2.5" SATA drives.
    - You want to boot from a USB flash drive and transfer the boot sequence to a M.2 NVMe SSD, correct?

    yes. the laptop can accept a NVMe ssd and can read/write to it, but the EFI firmware is blocked from launching the OS loader if it's on the NVMe drive.
    And i know this works because people who have this laptop on very old firmware versions could get it to boot by mashing the escape key to bypass the block, but a firmware update patched that workaround.

    I have an NVMe SSD. I just inserted a USB flash drive with a FAT32 partition on it. My Windows on the NVMe SSD is C: drive. The USB flash drive got drive letter F:. I just ran the command:
    Code:
    bcdboot C:\Windows /s F: /f UEFI
    I rebooted my computer from the flash drive and it booted into Windows on my NVMe SSD. That's all you need to do.

    My bad about the M.2 not being a Samsung

    That is what I meant on post #6
    As OP doesn't have a working Windows, he probably must install the Boot Manager on the USB drive using a Win 10 installation drive and running Diskpart - list volume to find the NVMe and USB drive letters under WinPE.

    Glad it worked for you! I'd recommend this little guy if you are going to stick with USB flash drive booting:
    SanDisk Cruzer Fit USB 32GB Flash Drive

    I use them as my boot devices for my TrueNAS server.
