Show or hide navigation and status bar when using dependency service...

I'm doing it on forms dependency service...
So I created a PageRenderer class:

[assembly:ExportRenderer (typeof(MyForms.HomeLayout), typeof(MyForms.iOS.HomeRenderer_iOs))]
namespace MyForms.iOS
{
public class HomeRenderer_iOs : PageRenderer
{
UITypeContent content = new UITypeContent();

        public HomeRenderer_iOs ()
            {
            }

    public override void ViewDidLoad()
            {
    base.ViewDidLoad();
    }
        {....}
        Method() => this.Add(content.View)
            {....}
        }
}

I created this PageRenderer class above, but it isn't on my Storyboard... How I'm doing it on forms dependency service, I can't do it on LayoutBuilder...
Or can i?

I can create a storyBoard and add it manually, but all on code?
