First off, I'm not very knowledgeable about the Bolt, but modern vehicles including many ICE vehicles now have 12v charging systems that are much more complex and many monitor the current (coulomb counting) of the 12v battery. So if you connect loads directly to the 12v battery, you can make whatever software is monitoring the charging system believe the 12v battery is failing. It will see the extra amp hours out and not back in as a battery with internal loads (sulfation) and could result in warning lights, or even damage to the 12v battery from overcharge/undercharge.
I know there's quite a few Tesla owners who found out the hard way that connecting large loads such as inverters to the 12v battery can cause warranty issues and can be responsible for out-of-pocket costs. On most EVs, there's going to be some way to derive 12v safely for extra accessory loads, but I can only comment on Teslas with expertise.
