Is it possible to map a 1000cc dirt bike ECU on stock hardware?

I’m looking at KTM 1000cc dirt bikes for adventure/off-road use and trying to understand the limits of the stock ECU. My dealer said the bike only supports two maps, Standard and Extreme and any updates require loading the latest software through their system. Old maps aren’t stored in their database. I want to know if it’s possible to load official KTM maps from a PC to the stock ECU myself or at least switch between maps without visiting the dealer every time. I’m only interested in official maps,no aftermarket tuning modules so there’s no compatibility or warranty concerns. Specifically: Has anyone successfully uploaded a map from their computer to the stock ECU on a 1000cc KTM model? Are the official maps downloadable anywhere? If I only want to switch between Standard and Extreme maps, is there a way to do this offline without the dealer? What software/hardware would be required for such operations? Any risks of bricking the ECU if I attempt this? I’ve seen some generic tools listed on Alibaba and other sites but I’m hesitant to use them without knowing their legitimacy. My goal is just to explore ECU mapping within KTM’s official framework not void warranties or damage the bike. Would appreciate any guidance from anyone who’s tried this on the big KTM models.
