Lightware Lidar Parameter Flag

Iam using Pixhawk2.1 with PX4 v1.7.2. After flashing px4fmu_v3_default app in hardware. In the parameters I could not find SENS_EN_SF1XX in sensor part. While using command param show which shows that SENS_EN_SF1XX is not activated. I want to know how to activate this sensor/flag.
