Workaround:
Call EnsureCoreWebView2Async() and then

Android:

public class WebViewCustomization
{
    internal static Android.Webkit.WebView? GetNativeWebViewFromTemplate(Microsoft.UI.Xaml.Controls.WebView2 webView2)
    {
        var webView = (webView2 as ViewGroup)?
            .GetChildren(v => v is Android.Webkit.WebView)
            .FirstOrDefault() as Android.Webkit.WebView;

        return webView;
    }
    public static void SetWebView(Microsoft.UI.Xaml.Controls.WebView2 webView2)
    {
         var web = GetNativeWebViewFromTemplate(webView2);
        if (web==null)
        {
            return;
        }
        web.Settings.MediaPlaybackRequiresUserGesture = false;
    }
}

Windows:

public class WebViewCustomization
{
    public static void SetWebView(Microsoft.UI.Xaml.Controls.WebView2 webView2)
    {
#if !DEBUG
        webView2.CoreWebView2.Settings.AreDevToolsEnabled = false;
#endif
        Environment.SetEnvironmentVariable("WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS", "--autoplay-policy=no-user-gesture-required");
    }
}
