Hi

No, any GPIO can be configured as an open drain. There are quite a few cases on how to configure PORT 1 pins already on the DevZone. Please find a case fitting the SDK you're using: https://devzone.nordicsemi.com/search?q=configure%20port%201%20pins 

Best regards,

Simon

in my case whenever, I am trying to configure port 1 pin as open drain that will not work.
