Non-free packages in Qubes and which are safe to remove?

Qubes R4.1 Dom0 packages reported unsatisfactory by vrms (Virtual Richard Stallman):

# vrms-rpm

24 non-free packages (2.0% of total)

Can I remove linux-firmware if I require no proprietary firmware?
Looks like several of these are false positives.

Debian-10-minimal:

None reported.

Fedora-32-minimal:

# vrms-rpm 
666 free packages (99.5% of total)
4 non-free packages (0.5% of total)
 - gobject-introspection
 - grubby-dummy
 - qubes-core-agent-systemd
 - qubes-libvchan-xen

Linux-firmware is the only one I would try. Definitely don’t try the kernel* packages. Microcode_ctl has spectre/meltdown fixes for Intel CPU. You can remove it if you have AMD CPU, but there should be a similar package for that which will probably have the same issue. A lot of the qubes-packages sound important too. If that tool is just looking at the license, you should reconsider. Stallman is really picky about licensing.

I strongly recommend against removing any packages from a minimal template, since it’s already minimal. Doing so will almost certainly break things. If you want to know which packages you can remove from a non-minimal template, you should probably just take the opposite approach instead: Start with a minimal template and add only the packages you want.
