Code is not uploading in arduino nano with atmega328pb microcontroller

[polaris221]

I have got this arduino nano board from china.
I could not upload code after I upload once with arduino Ide and Serial port is not opening.
The com port is detected by arduino ide.

It seems that this board have ATmega328PB instead of ATmega328P.
need help.
My Arduino IDE version 2.1.0

I had tried this.But problem is Arduino IDE is not opening the serial monitor.
Then I Tried with Serial1 with FTDI and it worked.Still it is very much inconvenient to use ftdi.
I think I am missing something
