The best way to prevent a tag from firing would be to adjust the loadrules to only be met for specific events.
Typically you would only have a "view" event fire once per page, there are some exceptions - but it may be worth confirming if you want to be using "utag.view" instead of "utag.link"

If the event data being sent for both of your view events is identical - and there isn't and easy way to be able to identify whether this is the second event on the page or not - You could look to add some functionality in one of a few places

• Tag Template - Some of our tags already have this functionality built in - lots of them will make use of a "u.initialised" flag which you can use. This would involve modifying the template though, which many people prefer to avoid.

• Extension / Loadrule update
  Add this code to a javascript extension which is scoped to the tag.

  utag.data.has_xxx_fired = true;

  Then add this code to a JavaScript Extension scoped to "Before Load Rules"
  

  b.has_xxx_fired = utag.data.has_xxx_fired || false;

  
  Then add this condition to a loadrule
  has_xxx_fired is not equal to true

You can change out the variable name "has_xxx_fired" with anything you like!
When the tag fires for the first time, we set has_xxx_fired in utag.data, which we then read on subsequent events, and we dont let the tag fire a second time.

Those options are a bit more work - And it would be easier if you already have something in your event to play from though.
