Recovery Partition for HiKey960

Hi all,
is it possible to have a separate recovery partition for HiKey?

HiKey recovery images are not built at all in AOSP. I guess its because recovery is stored on a separate flash and will start after setting the switches/jumpers only (so there is no need to build a recovery).
But maybe we can have a second recovery as a partition which we can use to boot into automatically. If yes, how to set this up in AOSP?
