You can't, but such a reconfigure should not take long. You can even
build the system in advance,
and it takes even less time. This way guixsd can guarantee, that you
have a generation for all your
changes, and can roll back. If you have not guix pulled between to
reconfigures, then they only do
the needed package installations and configurations. Usually reboot is
not needed either in these cases.

%desktop-services is just a list, you can simply cons* your nem
services, and use 'remove' to remove a service,
along the lines of:

   (remove (lambda (service)
               (eq? (service-kind service) avahi-service-type))
             %desktop-services)

You need srfi-1 to make this work.
This is documented in the manual here:
