Hello everyone,
I am using the fanstel BC840, where the tx and rx pins of the uart are alloced on 1.02 and 1.01:

So i have created a custom_board named hello_board, which is a copy of nrf52840dk.dts, where i am able to change the pins and ports of leds and buttons like this:

Everything works well, my question is, how i can change port and pin of the UART0? I want to use this UART0 to work with projects like central_uart or througthput:

i can see how to change pins but i don´t know how to change the port to 1.
Thank you, any help is welcome.
