The document style is comes from WinUI library, if you have used Microsoft.UI.Xaml nuget, and add the XamlControlsResources into application xaml, it will update radio button style automatically.

<Application.Resources>
    <XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
</Application.Resources>

And the dark theme radio button style meet your requirement. For more detail please refer Getting started with the Windows UI 2 Library
