Question about Roborock S8

Is the Roborock S8, 5GHz capable? Since the changeover in our region from 2.4GHz to 5GHz, our faithful servant Roborock S6MaxV, which is only 2.5 years old, no longer works. Connection cannot be established. The operating instructions and the app clearly state: (only 2.4GHz capable). Is it really not possible to update the device to 5GHz? What about the Roborock S8? I'm looking forward to feedback
