They are very much needed, but not to boot I think. They enable stuff
like seeing the battery level, etc.
protection-domain-mapper is in the archive
https://packages.debian.org/search?keywords=protection-domain-mapper
not sure why you have problems with that.
Same for qrtr-tools
https://packages.debian.org/search?keywords=qrtr-tools
and acpi
https://packages.debian.org/search?keywords=acpi
Back when I made my install one also had to manually enable the
service that comes with qrtr-tools, not sure if with newer version it
is enabled by default. It is called qrtr-ns so something like
# systemctl enable qrtr-ns.service

That's not where you have to do that stuff. It happens in the
firmware's command line. I don't think the firmware's GUI
configuration allows to create/edit entries.
