Facebook deduplication in Zaraz

Hi, I am testing the Facebook pixel/Conversion API tool in Zaraz. I do have the same Facebook pixel currently running on the site via. GTM but I would like to migrate the pixel to Zaraz and run it server-side. I was wondering about deduplication. I know there is an event ID template in GTM which can serve as a variable for the Facebook parameter event_id. Is there any built in deduplication in Zaraz since the pixel and the CAPI are configured together? Do I need to add an event_id parameter? Is there anyway to generate the event_id parameter in Zaraz or do I need to include it in the dataLayer? In the testing panel in Facebook I can only see a few events with the “deduplicated” adnotation.
