The current charger consists of up to three 24 amp modules. That's where 48 and 72 come from. It's a cost and regional accommodation so that three phase power can be used in Europe. Current US production eliminates one of these modules. There is only one box. You could swap in another 24 amp module from a loaner car. Or get an older 72 amp charger from a loaner car. Then you'd have to get the car to recognize it but it may be as simple as a forced update to all the car modules. The service center for instance does that on the interior ultrasonic alarm install. This process queries all the car modules and updates them from the current build.
Here’s an internal pic of a presumed gen2 72 amp charger illustrating this:
Can charge but cannot supercharge
