This seems excessive. Easier to disconnect it from the internet completely, and have it boot to HDMI1, hook up an external HDMI-CEC switch, and never think about it again.
With "Hotel Mode" you can make this effectively permanent and never see LG's UI again unless you want it.
Then just connect whatever HDMI-based box you want (Roku, Apple TV, Plex, Android, whatever) and use that for the content.
