ESP32-S3-Mini ---- UART0-1-2

Hi all,
I am designing a board with the ESP32-S3-MINI and I need 1 UART (UART0) for debug and 2xRS485 (UART1 and UART2 with RTS).
I plan to use the UART1 (IO17, IO18 and IO19) for the 1st RS485 interface.
For the 2nd RS485, which GPIOs can I use for TXD, RXD and RTS? Is it possible to choose the ones I want?
According to the ESP32-S3 datasheet, there is 3 UART so how can i chose the GPIOs for the 3rd UART ?
Is it possible?

Thanks

You can select them freely (same for the other UARTS) by passing the GPIOs you want to the initialization function.
