This morning I wasn’t able to find the binary and release notes for NSX-V 6.4.7. It turns this release was pulled overnight due to a bug – DFW Rule publish operation failed with service profile configuration in existing firewall rules in 6.4.7 (80238).
Update: VMware has released NSX 6.4.8 (10th August 2020) which resolves this issue. VMware NSX Data Center for vSphere 6.4.8 Release Notes
The issue is live and VMware have published the following KB https://kb.vmware.com/s/article/80238
