Searching for a dual channel wall mounted dual white dimmer

In an existing lamp, I want to place 2 (or more) dimmable (dump) light bulbs with different colour temperature.

With adjusting 1 of the dim values, the temperature should be set, when both are adjusted, the brightness should be set.

The controlling should be possible with a wall mounted dimmer, because I want to avoid using apps all the time, and it should be possible to operate the lights even if the wifi is down.

So far I’m having troubles to find a proper dimmer for this, and I’am hoping there is someone who can give me advice on this

Thanks in advance
