Rover rangefinder configuration issues

Good morning, I am developing a design of a Rover for the garden.

I have a Pixhawk 2.4.8 controller and a VL53LX0 sensor. Can it be used to avoid obstacles? “Dodge”
I connected the VL53LX0 and configured everything.
The sonarrange measures, however, I cannot enable the sonar options

thank you
