Disable white Channel on Shelly rgbw2

Hello i just buyed 2 Shelly rgbw2
But i only had some basic rgb strips left
Is there any way to disable the white Channel ?

When set the color to white it turns on the white Channel ( witch is not hooked up ) instead of setting R G B channels to 100% to get ´white ´

Very good question.
I have the same scenario. Would live to know how. Either from the Shelly side or HA side. Does anyone know? :slight_smile:
