Can the refresh rate of Dotstar APA102 LEDs be changed to ma

Dotrstars are great, but sometimes I like the flickering dot effect sometimes that the Neopixel light strips make when you move them. I have read that the Dotstar APA102s are designed to reduce flickering with 19.2Khz PWM. I tried lowering the brightness and that has not worked.

Is there any way to change the PWM of Dotstar LEDs to be similar to Neopixel?

Is there another way to control the refresh rate? Thanks!

This video from someone else shows an example of what I want. In the video the person doesn't want the dots to show up, but I do.

The PWM refresh rate is baked into the APA102 chips and it is not possible to change it.
