i.MX6UL Ethernet and UART muxing

I am using Ethernet 2 in RMII mode. Here ball No. G14(ENET2_TX_ER), I am using as a RMII error signal.

I am also using UART3, where the same pin(G14) is used as UART3_CTS. Since I am using G14 as ENET2_TX_ER, can I use UART3 port without CTS.

The i.MX processor tool(eclipse) is not giving error to use G14 pin as a ENET2_TX_ER.

I understand that if I am using UART3 signals like Tx, Rx and RTS, then I can not allow CTS to use for other purpose than UART. Please clarify my this understanding.

Best regards,
