IS it possible to change the polarity of the USART CTS/RTS pins on STM32F334

I am wondering how can I figure out the correct way of defining STM32F334 USART Hardware Flowcontrol pins (CTS/RTS) in StdPeriLib.
They should be PullUp/PullDown/NoPushPull or ....
Or better to say what should be the minimum commands set of commands for configuring the CTS/RTS pins for USART1.

I have to interface the MCU with a board which its CTS is active level is Low, In addition I can also set the board's CTS/RTS pins to PullUP/PullDown or Floating.

Is it possible to change the polarity of the CTS/RTS pins in the MCU?
Thnx
