Cube IMU maximum Gs

I was reading the datasheet of the IMUs present in the cube, namely ICM-20649, ICM-20948 and ICM-20602, where the 649 can read up to ± 30G in the 3rd full scale range. So im puzzled by the expression “full scale range” can that be somewhat tweeked in the cubepilot firmware.

In addition the other IMUs, the 948 and the 602 can read up to 16 Gs ±, but again they specify “full scale range” how can we, the cubepilot/pixhawk users, use that information?

Here you have the datasheets:
