I cannot change my wifi router settings and channel

I wanted to change my 5ghz wifi channel to a lower one so my nintendo switch could connect to it I went on 192.168.0.1 to change it and it showed me this message.   Wi-Fi Mode, Security Mode, Channel Selection, Channel Mode, and Channel Bandwidth are being managed automatically to help optimize your home Wi-Fi network and improve Wi-Fi coverage.
