Looks like it - I imagine using the existing mode button. It could be available as a TFT update but I’d be surprised if BMW offered it for free when they’re advertising it as a “new” feature.
Interestingly, and probably because so many people have bought them, the SatNav mount above TFT is apparently now a recognised end user part rather than being a slightly hidden, emergency services item. You do need the GSA (and now 850GS) adjustable screen mount, but it’s the most elegant solution if you do, with the added benefit that they’re now in stock (so next day delivery), rather than waiting 3-6 weeks for delivery from Germany. Stupidly expensive though - now about £105 in the UK!
However, I don’t really believe that the 2021 changes amount to much - LED indicators, Euro5, USB ports and a slight change to modes. Colours are marginally better on the 750 and the 40 years is OK. They could do with making the engine less rattly and noisy and the gearshift assist pro a bit smoother. And the crank case covers really need to be black like on the 900XR series - the silver paint seems to attract grime and I find them next to impossible to keep clean!
