I have a KNX-controlled RGBW light where each color channel (Red, Green, Blue, White) has:
A separate on/off switch (1-bit, DPT 1.001)
A dimming control (8-bit, DPT 3.007)
A brightness value (0-100%, DPT 5.001)
My goal
I want one single RGBW light entity in Home Assistant instead of separate lights.
is that possibl?

Probably yes with a template light.
So should I create a separate KNX entity for each color (Red, Green, Blue, White) and then combine them into a single light.template entity?

That's probably one way to do it.
I'm not familiar with the finer details of KNX so I can't say if that's how things are typically done on that platform.

Use the "individual addresses" tab in the color section of the Knx light entity creation panel.
You don't need the DPT 3 GAs, just on/off and absolute brightness.
Or do it in yaml if you prefer https://www.home-assistant.io/integrations/knx/#light - see "individual_colors" key. There is even an example in the docs.

But what should be the on and off switch ?

But what should be the on and off switch ?
you don't need a common on/off when using individual color configuration - it's optional then
from docs:
individual_colorsmap (optional)
Used when the actuator only supports individual group addresses for colors. Whenindividual_colorsis used the rootaddresskey may be omitted.
