I swapped only CTS and RTS using the CnfigTools for i.MX Version 9.0, but no error or warning. (TX, RX are unchanged)
Which register should be changed to switch the functions in use? Is it possible to replace CTS and RTS without changing TX and RX?

sorry this is not possible. For details one can look at Figure 55-2. UART external signals
to module signals routing with respect to DCE/DTE mode
