The .NET MAUI DataGrid allows you to disable grouping dynamically by clearing the GroupColumnDescriptions collection. Additionally, if you want to remove grouping when there's only one group, you can use the following code snippet. The code below illustrates how to dynamically disable grouping for a specific scenario.

C#

public MainPage()
{
   InitializeComponent();
   viewModel.InstalledModels.CollectionChanged += InstalledModels_CollectionChanged;
}

private void InstalledModels_CollectionChanged(object? sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
{
   if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add)
   {
   	if (datagrid.View!.Groups.Count() == 1)
   	{
   		datagrid.GroupColumnDescriptions.Clear();
   	}
   }
}
