Note there are different requirements for VCP-NV 2020 depending on whether you take the NSX-V route or NSX-T route.
NSX-V works with vSphere, therefore the VCP-NV 2020 that includes the NSX-V exam also requires that you pass the vSphere Foundations exam:
VMware Certified Professional - Network Virtualization 2020 | IT
As NSX-T does not require vSphere in order to be deployed, the VCP-NV 2020 that includes the NSX-T exam does NOT require that you pass the vSphere Foundations exam:
VMware Certified Professional - Network Virtualization 2020 (VCP-NV 2020)
This is regardless of whether you are Cisco certified or not - the only difference with being Cisco certified is whether you have to attend NSX training or not.
