How to group a column in the actual order without sorting the data in SfDataGrid?

public partial class MainPage : ContentPage
{
        private SfDataGrid dataGrid;
        private ViewModel viewModel;
        public MainPage()
        {
            InitializeComponent();
            dataGrid = new SfDataGrid();
            viewModel = new ViewModel();
            dataGrid.ItemsSource = viewModel.OrdersInfo;
            dataGrid.GridViewCreated += DataGrid_GridViewCreated;
            dataGrid.GroupColumnDescriptions.Add(new GroupColumnDescription() { ColumnName = "CustomerID" });
            this.Content = dataGrid ;
        }
        private void DataGrid_GridViewCreated(object sender, GridViewCreatedEventArgs e)
        {
            dataGrid.View.BeginInit();
            var groupColumn = dataGrid.View.SortDescriptions.FirstOrDefault(x => x.PropertyName == "CustomerID");
            dataGrid.View.SortDescriptions.Remove(groupColumn);
            dataGrid.View.EndInit();
        }
}
