I think it could be interesting to explore Universal Blue based distros such as Bazzite for this kind of use cases. The OS comes from a standard OCI container image, which means you can create your own customized one by layering changes on top of an upstream base image.

I feel bad for the unsolicited distro plug though especially since you already have a solution that works well and you are familiar with, but I thought it might still be useful to mention it. I'm not sure if uBlue would even be better vs your current setup. Seems like netboot would still be needed to get the latest version without an extra reboot.
