You cannot disable automatic HDMI switching on certain models, but you can add an HDMI switcher in order to have only one HDMI adapter to worry about. By tricking the system into thinking it only has one HDMI port open, you eliminate the problem, but at your own expense rather than with Samsung’s assistance.
