Question Charging battery via 12v outlet? / Keeping trunk 12v hot

Hey there Cayenne fans -

I'm looking to help out my Dad, who recently received a 2020 Turbo and needs a solution for keeping the battery maintained/trickle-charged.

It would be convenient to be able to trickle charge via the trunk 12v outlet, however power seems to cut to that after 30min or so with the ignition off.

Is there any way to keep the rear outlet (or any of the outlets) hot all the time? I'm not finding anything quickly in the documentation, and the dealer seemed confused.

We can of course wire directly to the battery but it's less convenient to connect/disconnect.

Any thoughts appreciated - thanks!
