What have " circled" is the control valve and what you " X" is the diverter valve. You are correct, not needed if you are not using the air injection system.

In case you want to know what these do:
The control valve is boost activated and measures a certain amount of pressure and then sends that pressure to the diverter valve, opening the diverter valve to divert air away from air injection system during boost conditions.
