Flashing TYWFC6-14 for 4-Channel RGBW Integration in Home Assistant

I flashed a 4-channel RGBW controller (TYWFC6-14) with the openBK firmware. (this one: https://device.report/m/cb83b8d16a1226f220c9c54c2ba36cdec3655cad0582d41ec4a18ed605c6321d)

Everything works well, but I have a problem with the Home Assistant integration.
If I integrate it as a 4-channel RGB controller or as a 6-channel RGB+CT, it works. But I'm unable to integrate it as a 4-channel RGBW controller.
How can I make it so it has RGB plus a white channel but not a second white channel?

With 6 channels set, the generated YAML is:


But if I change it to 4 channels, the YAML changes to the following (which does not work):

Hello, would you like to integrate it as RGB + W , or maybe as emulated RGBCW? There is a flag for RGBCW emulation with RGBW in OBK.

Ideally, I think I would like it to completely ignore the color temperature. Meaning warm white and cold white should both map to the single white LED.
