Something like this?

// Drag the camera you want here in the editor.
public Camera cam;

void Awake(){
   cam.fieldOfView = 90.0f;
}

You need a Camera variable to hold the Camera you wish to modify.
I am not sure what scripting language you are using, so I shall just put down Java, and C# examples.

C#:

 public Camera myCamera;
    
    // Then, to modify the camera's FOV, do this:
    myCamera.fieldOfView = 10f;

Java:

public var: Camera: myCamera;

// Then, to modify the camera's FOV, do this:
myCamera.fieldOfView = 10f;

First of all you have to set your camera in to 3D projection = perspective
then u get the FOV option!!!

public Camera camera;

void Awake()
{
camera.fieldofView = 15f;
}
