How to close the automatic aperture of Sony x580 camera?

Can't close it. Automatic aperture is a function of the camera and cannot be turned off. When using a single automatic aperture, as long as the PUSHAUTOIRIS button is pressed, the camera will automatically adjust the aperture to obtain the best exposure effect. When you press and hold this button, the sign of automatic aperture will appear next to the aperture value on the screen.
