It wouldn't be too old. The update is available for all G30s build after July 2019 (MY2020). I have it on my 530e with a 9/5/2019 build date, for instance.
The newer hardware for RSU and other functionality was added starting July 2020 (MY2021).
If your car "can't accept" the update the dealer should be able to replace the defective parts under warranty until it does. I would use one of the many TSBs to convince them to do the update to ensure everything is warranty covered.
