You can add events to nodes dataLabels using js addEventListener like that:

  chart: {
    type: 'networkgraph',
    marginTop: 50,
    events: {
      load: function() {
        var nodes = this.series[0].nodes;

        nodes.forEach(function(node) {
          node.dataLabel.div.addEventListener('click', function(e) {
            console.log('click')
          });
        });
      }
    }
  }
