IMU ICM42670P freefall and SMD

I want to use the IMU to continuously read accelerometer and gyroscope values while also enabling Freefall and SMD (Significant Motion Detection) interrupts. However, the application note mentions that the power register needs to be set to 0x02 for Freefall and SMD detection, which puts the accelerometer on low power mode and turns off the gyroscope. Is there a way to enable Freefall and SMD detection without switching the power register, or is changing the power register the only option? If there’s an alternative configuration or register setting, please advise.
1. During freefall testing, when the product is released from a certain height, only the low-g threshold is triggered, and freefall is not detected. Is there an alternative method or approach to test freefall detection more effectively?
2. According to the application note, the accelerometer operates in low-power mode, allowing its values to be used. However, what is the expected behavior or usage of the gyroscope values in this scenario? Should the gyroscope also be configured or considered in any other setting because if i change the power management the apex features not working. please advise on this also.
