By default, the PHY mode of ESP8266 devices is 802.11bg mode, and the PHY mode of non-ESP8266 devices is 802.11bgn mode. Can ESP8266 support 802.11bgn by default by modifying the code?

I need ESP8266 to support 802.11bgn mode by default without sending the AT+CWSTAPROTO command. How should I modify the code?
