I may not understand your question entirely, but what if you put a contactor in between the battery and your auxiliary devices? Then you can set up charger to open the contactor when it's plugged.
Isolating DC-DC exist, but it's going to cost a fortune given the required voltage and power capabilities.
Can you elaborate on type of battery and charger that you're using? Are you getting particular error code from the charger? In tesla all the auxiliary stays on during the charging session.
