vSphere Endpoints Maximum - vRA Large Deployment

Hello ,

I have a large distributed vRA Envrionment with 3 Node vRA Appliance.

As per VMware official document  (vRealize Automation Hardware Specifications and Capacity Maximums ), maximum vsphere endpoints can be only 20 for vRA 7.4.

I have more than 80 vCenters to add as endpoint to my vRA Environment.

Will my existing environment support this many endpoints or what will be my approach , do i need to have multiple vRA environments to handle such a massive environment.

Please suggest.
