There is no built-in option, but you can use wpdatachart callbacks. Every chart exposes several options that customize its look and feel. Charts usually support custom options appropriate to that visualization. You can use it for adding options that are available in Highcharts API. In this callback in method wpDataChartsCallbacks 19 is the ID of the chart which you want to change. Insert this script above shortcode of your chart on the page.

<script type="text/javascript">
jQuery(window).on('load',function(){
    if( typeof wpDataChartsCallbacks == 'undefined' ){ wpDataChartsCallbacks = {}; }
    wpDataChartsCallbacks[16] = function(obj){
        obj.options.plotOptions = {
            series: {
                     dataLabels: {
                        enabled: false
                     }
            },
            pie: {
                  allowPointSelect: true,
                  cursor: 'pointer',
                  dataLabels: {
                       enabled: false
                  },
                  showInLegend: true
            }
        };
    };
});
