Short answer is no - there is no out of the box way to pass svg file and display it out of the box in RadMap.
However, we think there is a workaround:
this great tool can transform SVG file into ImageSource. So you can prepare Image object in code and use it in RadMap's VisualizationLayer / Informationlayer. Or you can transform the svg into png / jpg file and use it into UriImageProvider
