SoundTouch Lifestyle 650 souce select

Hi folks,
Fairly new to HA but have had good success so far with my limited knowledge.

I have a Bose Soundtouch Lifestyle 650.
Is it possible to select a HDMI source instead of preset playlist?

Seeing as Bose hasn’t added AppleMusic yet I dont have a lot of need for the presets but I do often stream from our apple tv. Unfortunately CEC on our TV doesn’t perform consistently with the Bose system so we have had to turn it off but i was wondering if HA might be a good work around.

I’m able to do it in php with rest API but don’t know if it’s already possible with home assistant or how to script it.

Thanks for your help
