UART functionality without RTS & CTS

We have a custom board design with i.MX 8M Nano processor. In this we are using all the 3/4 UART instances.

UART3_RXD - E18
UART3_TXD - D18

We have not connected RTS & CTS as we don't require hardware flow control.

Is it possible to connect the UART without RTS and CTS?
