Any such setting would be device dependent.

Using https://www.mathworks.com/help/supportpkg/usbwebcams/ug/set-properties-for-webcam-acquisition.html you might be possibly see a directly relevant setting; if not then you might be able to use Iris and Zoom; https://en.wikipedia.org/wiki/Angle_of_view#Measuring_a_camera.27s_field_of_view
