@WZ9V, The NVMe slot can be made bootable. Their are lots of U-Boot options.
The safest is to use the eMMC as the U-Boot target and have "/boot" on the eMMC. But, some people have both "/boot" and "/" on their NVMe, (with U-Boot still on the eMMC.)
You can install U-Boot on the SPI flash device. It's the first bootable target, (SPI, eMMC, SD card, & specialized USB). If that U-Boot has support for the NVMe, you can remove the eMMC completely and boot everything off the NVMe device.
I recently installed some new U-Boot software that includes keyboard, display, several menus and makes things MUCH nicer. But, their are caveats, it does not work with Manjaro's 5.7 kernel. So that Pinebook Pro is booting the original Debian. (Linux kernel 5.8 or later is expected to solve that boot problem.)
