Is there any way to set IndicatorStackLayout.HorizontalOptions of indicatorView to LayoutOptions.FillAndExpand?

Question

Is there any way to set IndicatorStackLayout.HorizontalOptions of indicatorView to LayoutOptions.FillAndExpand?

I wrote the following code in the constructor of MainPage.xaml.cs

public MainPage()
{
	InitializeComponent();
	var sl = (idcView.IndicatorLayout as StackLayout);
	sl.HorizontalOptions =LayoutOptions.FillAndExpand;
}

but after running the program, I found that IndicatorStackLayout.HorizontalOptions automatically becomes LayoutOptions.Fill, is there a way to solve this?
