Turn RGBW to RGB

Hi
I have my RGB LED Strips controlled by either a rgbw zigbee or rgbw shelly controller.
Since they are compatible with my rgb strips it works most of the time.

However if I ask google to do sunlight or other kinds if white it tries to use the White channel of the LED, resulting in a greenish yellow…

Is it possible to disable the white channel and turn my entety from RGBW into only RGB?
