Entra Cloud Sync agents skipping local AD config

Some of our VMs that contained Cloud Sync agents were lost. We recreated the VMs and reinstalled the Cloud Sync provisioning agent. The provisioning agent wizard is skipping the on-premises AD configuration part and going straight to the Azure AD connection configuration. This way, the cloud sync agents are in the "not configured for xxx domain" state, so we can't add new agents for redundancy. There's any way to force "local AD" connection or at least configure new agents for an already configured domain?

We are relying on a single agent. We did a test of killing this agent and reinstalling it and we were left with no agent and no possibility to create new ones. We had to restore the VM to get our synchrony back. Any help would be awesome.
