(Navimow i2 AWD) Why can’t I select the Ride-on Boundary option when setting the boundary?

The Navimow i2 AWD currently supports a single boundary mode. When no obstacles are present, the mower will follow the boundary. If it detects obstacles such as walls or steps, it will automatically avoid them.
The mower can intelligently determine in real time whether it needs to follow the boundary, so there is no need to manually select a Ride-on option.
