Issue with NVIDIA A10 graphics card not recognized on Azure Windows 10 VM

Question

I have created an Azure virtual machine Standard NV12ads A10 v5 with Windows 10 Pro and installed the NVIDIA A10 graphics card drivers. In the Windows 10 Task Manager, I can see the NVIDIA A10 graphics card listed, indicating that it is functioning correctly.

However, when I run the dxdiag command, it shows the graphics card as Microsoft Remote Display Adapter instead of the NVIDIA A10 graphics card.

Furthermore, I have developed a WPF application using Visual Studio 2019 and .NET Framework 4.7.2. The purpose of this application is to display a 3D model from an .obj file using the HelixToolKit.Wpf v2.5.1 library. The application works fine on my local PC with an NVIDIA GTX 970 graphics card. However, when I run the application on the Azure server, it experiences low FPS. The main components of the application are the XAML and C# files as follows:

MainWindow.xaml:

<Window x:Class="TestHelixtoolkit.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:helix="http://helix-toolkit.org/wpf"
        Title="Model Viewer" Height="600" Width="800">
    <Grid>
        <helix:HelixViewport3D
            x:Name="Viewport3D"
            ZoomExtentsWhenLoaded="True"
            Background="Black"
            Orthographic="False"
            CameraRotationMode="Trackball"
            ShowViewCube="False"
            ShowCoordinateSystem="True"
            IsHeadLightEnabled="True"
            CalculateCursorPosition="True">
            <helix:SortingVisual3D Method="BoundingBoxCenter" CheckForOpaqueVisuals="True" SortingFrequency="1">
                <ModelVisual3D Content="{Binding ModelVisual3DContent}" />
            </helix:SortingVisual3D>
        </helix:HelixViewport3D>
    </Grid>
</Window>

MainWindow.xaml.cs:

using System.IO;
using System.Reflection;
using System.Windows;
using System.Windows.Media.Media3D;
using HelixToolkit.Wpf;

namespace TestHelixtoolkit
{
    public partial class MainWindow : Window
    {
        public Model3DGroup ModelVisual3DContent { get; set; }

        public MainWindow()
        {
            InitializeComponent();
            DataContext = this;
            var fileLoader = new ModelImporter();
            var model3D = fileLoader.Load("path\to\file.obj");
            ModelVisual3DContent = new Model3DGroup();
            ModelVisual3DContent.Children.Add(model3D);
        }
    }
}

I suspect that the Microsoft Remote Display Adapter listed in dxdiag is causing the low FPS issue in my WPF application on the Azure server.

What could be the cause of this issue, and how can I ensure that the NVIDIA A10?
