The STM32F777 has a bullet under Section 2.25 [U(S)ART] :

Swappable Tx/Rx pin configuration

Where can I find more detailed information on Swapping the Tx/Rx pin configuration for a UART ?

The reference manual is usually the best source of detailed information:

Take a look at the SWAP bit in the USARTx->CR2 register.
