I don't think so, I think they can change it with the motor in the car.
You could attempt this in car, but it's not the wisest idea. To do the rear main seal you need to have clearance around the crankshaft to put it in. This means unbolting the connecting rods and at least loosening all the mains. You also have to unbolt the trans. Then manipulating it in while under the car and working around everything is a nightmare. You would be miles ahead and get a lot better job if you just pull the engine.
