It is a bit unclear to me to be honest. I think it is not affected because Cloud director (https://kb.vmware.com/s/article/87068?lang=en_US) is on the list of NOT impacted products.
I also see a line that Tenant App for vROPs is removed in the changelog. And it is not listed on https://www.vmware.com/security/advisories/VMSA-2021-0028.html as affected.
If you want to be sure i recommend to contact VMware.
