  plotOptions: {
    series: {
      states: {
        inactive: {
          opacity: 1,
        },
      },
      dataLabels: {
        enabled: true,
        inside: true,
        format: '{y}',
        showInLegend: false,
      },
      stacking: 'normal',
    },

    bar: {
      stacking: 'normal',
      borderWidth: 0,

        hover: {

Use format function

plotOptions: {
        series: {
          states: {
            inactive: {
              opacity: 1,
            },
          },
          dataLabels: {
            enabled: true,
            inside: true,
            format: function(){
               return (this.y != 0) ? this.y : "";
            },
            showInLegend: false,
          },
          stacking: 'normal',
        },
    
        bar: {
          stacking: 'normal',
          borderWidth: 0,
          states: {
            hover: {
              enabled: false,
            },
          },
        },
      },

You need to use formatter function for data labels. For example:

  dataLabels: {
    ...,
    formatter: function() {
      return this.y || '';
    }
  }
