Restart just 1 component? (Or start the Roku component in fake standby?)

In the new Roku component, can a flag be added for “start_off” like the Apple TV component such that it doesn’t start the setup until the configured player is turned on? I have a TCL Roku TV and it isn’t on when Home Assistant is started most of the time, so I have to restart HA after I turned on the TV.

Alternatively, is there a way to reload just the Roku component later on?

Thanks!
