    Can it be done without Prism?

    Yes, Prism build in Uri navigation routing. If you want to navigate, you can get the URL, based on different value of URL, then use Xamarin.Forms Navigation to do it. Firstly, Install the Xamarin.Forms.AppLinks NuGet package into the Android application project. Then, In the MainActivity.cs file, add a declaration to use the Xamarin.Forms.Platform.Android.AppLinks namespace and add IntentFilter above the MainActivity like following code. As note, you can change the value of DataScheme, DataHost and DataHost by your needs.

    [Activity(Label = "FormsAppLinking", Icon = "@mipmap/icon", Theme = "@style/MainTheme", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation | ConfigChanges.UiMode | ConfigChanges.ScreenLayout | ConfigChanges.SmallestScreenSize )]
        [IntentFilter(new[] { Intent.ActionView },
            Categories = new[]
            DataScheme = "http",
            DataHost = "deeplinking",
            DataPathPrefix = "/",
            AutoVerify = true)
        public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
            protected override void OnCreate(Bundle savedInstanceState)
               Xamarin.Essentials.Platform.Init(this, savedInstanceState);
                global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
                LoadApplication(new App());

    Then open your App.xaml.cs, and override the OnAppLinkRequestReceived method,

    protected override async void OnAppLinkRequestReceived(Uri uri)
             var data = uri.ToString().ToLowerInvariant();
                //only if deep linking
                if (!data.Contains("id"))
               var id = data.Substring(data.LastIndexOf("/", StringComparison.Ordinal) + 1);
               //Navigate  and transfer id here.
               await  MainPage.Navigation.PushModalAsync(new Page1(id));

    In the end, we can get the id in the Page1.

    public partial class Page1 : ContentPage
            private string id;
           public Page1(string id)
                this.id = id;

    Here is a document about Application Indexing and Deep Linking, you can refer to it.

    Best Regards, Leon Lu
