@change after page load

I have a v-on:change i only want to work after the page has rendered

<flat-pickr
    class="form-control date-with-time-inputs font-size"
    :config="config"
    v-model="pickUpDate"
   @change="changeDate()"
 ></flat-pickr>

I’m not even sure if this is possible, I have some data from param on load which I don’t want to trigger the event
