Can I use the NBI Certificate or receipt to substitute NBI Clearance?

got a round trip ticket for aug 24 - 28, however, my NBI clearance is still not released because of the new system and machine and it takes 3 - 4 weeks. I only have the NBI Certification and the OR receipt. Is this possible? Can I just pass the Original NBI clearance once it will be released ASAP? (To follow)
