[SOLVED] How to not trigger reactivity on update?

In a route data() function I would like MyCollection.find() to be reactive in most cases.
But for one case I update this collection and I do not want reactivity to be triggered.
If the Collection.update function had a {reactivity: false} option that would solve my case.
How to to it ?

I suppose you could use Meteor methods instead or pub / sub, in this case.

Removing reactivity for all the use cases just to answer one case scenario is not what I wanted to do.

I solved my problem by putting the value that triggered reactivity in a new collection (joined to the main collection). So the main collection is not changed, just the dependant information in the other collection.
