Interesting. Since building w/o fat bootfs works just fine may I ask why you need this?
Also /boot/firmware is fat32 by default from what I can see in the build logs.

The boot partition allows users of our operating system to configure settings before the initial startup. This workflow is currently implemented on Banana Pi and Orange Pi devices. For Raspberry Pi-based boards, we currently rely on Raspberry Pi OS Lite. However, our goal is to streamline and unify our build pipeline by transitioning entirely to Armbian.
