Yes, but you can’t change the default launcher in the settings. You have to configure the custom launcher to automatically launch everytime, which does require a some adb commands, if I recall correctly.

Otherwise, setting it to apps mode is the only alternative. Aside from disabling ads, it does disable a few other useful features, but the trade-off is worth it.

But honestly, now that AppleTV allows VPNs and proxy apps, I’ve mostly stopped using my Google TV boxes.
