Override default kasa wifi light switch to control smart bulb?

Is it possible to override the behavior of a mains wired kasa WiFi light switch? It currently controls power to the connected assembly (which is a fan/light combo), but I’d like to override that behavior, and have it control things in Home Assistant without managing power to the assembly.

Is that possible?

Did you ever find an answer to this?

No, I’m not sure it’s possible
