When using two CAN GPS devices with GPS_TYPE2, set it to 9 to configure the communication type of GPS2 as DroneCAN.
There is no need to change CAN_D1_PROTOCOL. It is set to 1 by default, which configures the virtual driver of CAN1 as DroneCAN.
There is no need to change CAN_D2_PROTOCOL. It is set to 1 by default, which configures the virtual driver of CAN2 as DroneCAN.
There is no need to change NTF_BUZZ_TYPES. It is 5 by default. Changing it to 1 will turn off the buzzer.
NTF_LED_BRIGHT doesn't need to be changed. It is used for adjusting the brightness of the status light. The default value is 3, and setting it to 0 will turn off the side indicator lights.
