The user must re-lock the pins after such a modification.

When settings are changed that alter what pins a driver requires, if the user has already locked those pins, they will become unlocked. The user must re-lock the pins after such a modification.
I have a UART configuration with Peripheral, TX Pin and RX Pin locked. I open the configuration in SysConfig (in CCS) and I enable Flow Control. At this point, the Peripheral, TX pin, and RX pin configurations are lost. Furthermore, different TX and RX pins are selected and the original pins are assigned to CTS and RTS.
The locked configurations should be preserved when Flow Control is enabled or disabled.

CCS 9.3.0
Here is the original locked configuration:
Peripheral: UART1 (locked)
TX Pin: DIO1 (locked)
RX Pin: DIO0 (locked)
After I enable Flow Control, I get this new configuration:
Peripheral: Any(UART1)
TX Pin: Any(DIO12)
RX Pin: Any(DIO11)
CTS Pin: Any(DIO1)
RTS Pin: Any(DIO0)
There is a similar behavior when I lock my configuration with Flow Control enabled, and I disable Flow Control.
