Samsung QN90D - The Message Connecting to Anynet+ Device; The Anynet+ Device Wont Play

I want to exit Anynet+. It is inconvenient to turn on other devices because
the TV also turns on. It is inconvenient because the connected devices (e.g.
set-top box) turn off together.
To turn off the Anynet+ function of a device connected to the TV, turn off the Anynet+ (HDMI-CEC) function of the
device.
