Sounds to me like you’re now already a VCP-DCV 2021, you’ve met all the requirements of the “no VCP and want to test on vSphere 6.7” path on the page I first linked to.
Login to Certification Manager and check: https://mylearn.vmware.com/api/?mL_method=sso&h=1625&target=CertMetrics
Email certification@vmware.com in a couple of days if you don’t see a VCP in your Certification Manager.
