I was thinking that you'd practice the battery swap at the same time as you're letting the 12V recharge with the car "On", so locking wouldn't be an issue.
But if you do lock it while running with the key outside the car, for the most part nobody will even know that the car is "On". The ICE will shut off when the traction battery is sufficiently charged, and the 12V will be recharged off of that silently. That may eventually drain the traction battery to the point where the ICE needs to recharge it again, but those periods should be relatively short and for the most part the car should be silent and look like any other parked car.
