Use a standard Gentoo aarch64 (arm64 ) package. Add a pi kernel, the /lib/modules directory and the /boot directory from a raspian tarball.
I did this on a pi 3B running in 64bit mode. Once I had a bootable system it was easy to modify and a fork from my first image is also running on a couple of odroid 64bit systems (using the odroid boot and kernel) and as an lxc image on a 64bit odroid n2. Getting the /boot directory and uBoot config files sorted was the main problem. BillK Use the equivalent from your local mirror.
