Change icon colour for "ON" status of a switch?

Is there any way to stop a switch component changing it’s icon to yellow when it’s turned on?

It’s fine for lights but I’ve got switches that control other things like TVs and the yellow icon isn’t as visible as the blue and doesn’t really make sense. I’d prefer the icon to stay the default blue like a group switch does.

Anyone any idea if this can be configured? I couldn’t see anything in the customization documentation.
