DRV8889-Q1: DRV8889-Q1 Decay mode setting

Part Number: DRV8889-Q1

Hi Team

The current customer new project's  motor has high-frequency noise. DRV8889-Q1 has tried the following Decay mode settings. The setting value is 110b, which improves the high-frequency sound, but there is still high-frequency sound. Is there any risk for setting the following value to the motor setting? ? Does it have a bonus effect on the improvement of high-frequency sound?
