How can I make some events are clickable or others not in Timeline Highchart?

Question

I have data like this:

var data = [{
    x: Date.UTC(1951, 5, 22),
    name: 'First dogs in space',
    label: 'fds',
    dataLabels: {
        allowOverlap: false,
        format: '<span style="color:{point.color}">● </span><span style="font-weight: bold;" > ' +
            '</span><br/>{point.label}'
    },
}, {
    x: Date.UTC(1957, 9, 4),
    name: 'First artificial satellite',
    label: 'First artificial satellite',
}, {
    x: Date.UTC(1959, 0, 4),
    name: 'First artificial satellite to reach the Moon',
    label: 'First artificial satellite to reach the Moon',
}, {
    x: Date.UTC(1961, 3, 12),
    name: 'First human spaceflight',
    label: 'First human spaceflight',
}, {
    x: Date.UTC(1966, 1, 3),
    name: 'First soft landing on the Moon',
    label: 'First soft landing on the Moon',
}, {
    x: Date.UTC(1969, 6, 20),
    name: 'First human on the Moon',
    label: 'First human on the Moon',
}, {
    x: Date.UTC(1971, 3, 19),
    name: 'First space station',
    label: 'First space station',
}, {
    x: Date.UTC(1971, 11, 2),
    name: 'First soft Mars landing',
    label: 'First soft Mars landing',
}, {
    x: Date.UTC(1976, 3, 17),
    name: 'Closest flyby of the Sun',
    label: 'Closest flyby of the Sun',
}, {
    x: Date.UTC(1978, 11, 4),
    name: 'First orbital exploration of Venus',
    label: 'First orbital exploration of Venus',
}, {
    x: Date.UTC(1986, 1, 19),
    name: 'First inhabited space station',
    label: 'First inhabited space station',
}, {
    x: Date.UTC(1989, 7, 8),
    name: 'First astrometric satellite',
    label: 'First astrometric satellite',
}, {
    x: Date.UTC(1998, 10, 20),
    name: 'First multinational space station',
    label: 'First multinational space station',
}];

Here is the fiddle link for your reference: Fiddle

In which I want some clickable event or others not according to my condition. Ex: If the label name is "First artificial satellite to reach the Moon" and "First soft landing on the Moon" It won't be clickable and others are clickable.

You could check if it is "not clickable" within the click processing (JSFiddle). First define those labels not clickable:

var unclickable = ["First artificial satellite to reach the Moon", "First soft landing on the Moon"];

Then implement the check in click to prevent processing, as well as showing the default cursor when hovering the points in mouseOver:

series: [{
  point: {
    events: {
      mouseOver: function() {
        if(unclickable.includes(this.label)) {
          this.dataLabel.element.style.setProperty('cursor', 'default');
          this.dataLabel.text.element.style.setProperty('cursor', 'default');
        }
      },
      click: function(data) {
        if(!unclickable.includes(this.label)) {
            // ...
        }
      }
    }
  }
}]

Be aware that your example JSFiddle had some   characters in the labels, which meant that regular didn't get a match when checking for includes. Make sure you have only regular spaces, or you have to be very exact when matching the label against another string.
