Note: Take a snapshot of the appliance before modifying these changes.

1. Connect to vRA appliance using root credentials.
2. In /etc/vcac/enabled-features.properties
3. Set SkipChangeBgDeploymentTopologyValidationEnabled = true
4. Restart vcac-server service for the changes to take effect.

In a clustered environment, apply the change to all vRA nodes.
