I don't know firsthand, but "Debian" is primarily responsible for userspace binaries, which just need to be built for aarch64. Just about everything specific to the chip & peripherals is handled in the kernel. (Yes Debian has a linux-image deb but I don't think anyone uses that on ARM. You build your own kernel.)

I am oversimplifying a bit, but you should be able to take these instructions [1], combine with a kernel and bootloader built for this board, and write the resulting image to eMMC/flash. You need to configure a few things correctly, boot cmdline & bootloader options but that's it.

Source: have used debootstrap to build custom distros for a couple ARM modules as well as x86.
