Can i use RxD pin as a normal pin during one way hardware serial communication ?

Using Arduino Programming Questions
1

I want to make a circuit, with Arduino Pro Mini, to use only the hardware transmitter of the serial. I have not write the code yet, it depends on the answer.
I want to ask if I will not enable the Bit 4 (RXENn: Receiver Enable n) on UCSRnB – USART Control and Status Register n B, can I use RxD pin, like a normal pin?

Here is the definition of the manual for Atmega328p on page 193:
Bit 4 – RXENn: Receiver Enable n
Writing this bit to one enables the USART Receiver. The Receiver will override normal port operation for the RxDn pin when enabled. Disabling the Receiver will flush the receive buffer invalidating the FEn, DORn, and UPEn Flags.

Thank you!

Yes, it can be used as normal I/O. That is reason why this enable/disable mechanism exists.
