How do i choose this with the esp-idf? Do i just set the port for the uart to whatever pin I want (with the exception of some reserved ones...)

An ESP32 has 3 UARTs available to it. UART0 is by default used for flashing and log. UARTs 1 and 2 are wide open to you. You can map the RX, TX and other pins as you desire.
See here for more info.

Thanks a ton! I was getting confused as to what is on the ESP32 and what is in the WROVER32-I module I am using. I appreciate the assist.
