Can I disable the ability to adjust color of a light entity?

Not sure why, every Xiaomi bulb I had has issue with color setting, if HA or HomeKit try to change its color, it’ll stick at low brightness. The brightness and switch are both work fine as long as color is not changed.

I hope to find the fastest way to make those lights’ color setting not adjustable, in both HA and HomeKit, so people in the same house don’t need to worry about “touch a wrong button”.
Template Light is a way to solve this, but then I have to make a new template every time I add a light entity. It’s okay, but I think there should be a better way to do this.

Any suggestion would be appreciated.

I would also like to know. I have bulbs that can do temperature and color. I would like to disable color. Is that possible ?

any news? I also have some bulbs that offer rgb support in home assistant, but don’t really support rgb. I would like to disabled rgb in home assistant for this bulb.
