Downgrade firmware?

[yarrr]

Is there an archive of previous firmwares for the Enterprise series?

I'd like to downgrade my controller to v02.01.00.03

Unfortunately, I can't find anything but the most current on the dji website and within DJI Assistant 2.

Chatted with DJI support- they stated that controller is not downgradable.
