Configure Dim Rate Parameter on GE Dimmer Switch

When logging in to manage my device from graph.api, I am not finding a parameter to adjust the Dim steps and levels. Is this a parameter that needs to be added for adjustment. Has anyone else successfully modified the default settings?

check out the “gentle wake up” code. Its basic function is to increment a dimmer over a period of time. it is a huge app though. ~700 lines

Thanks, Brian! Appreciate the feedback.
