Are you able to use a DC to DC charger to charge off car alt with these all in one systems?

Every one that I'm aware of.

The all_in_ones include an ac2dc charger and a solar charge controller.
The dc2dc charger is just another charge source.
You do need to make sure that the charge parameters of each source are compatible with your battery bank.
