I am interested to know how control of dim2warm works. More precisely, I would like to know how dimming and color temperature works. Do you have specific hardware for this, or can you recommend compatible options?

In case of this smart array you cannot control color temperature independently from light intensity. The Dim2warm functionality is 'controlled' by the operating current. Lower current results in lower color temperature (due to the different current / voltage characteristics of the involved warm white and cold white LEDs and their series resistors).
Most probably it would be possible to break the connection between the warm white and cold white LEDs on the PCB and control both independently with two different current sources (just remove the series resistors).
