Is there a way to have my proxmox servers show up under "datacenter" without setting them up in a cluster?

Question:

Is there a way to have my proxmox servers show up under "datacenter" without setting them up in a cluster?

Background:

Because I am unknowledgable, I had issues in the past with the cluster functionality, quorum and how the files in /etc/ are frozen and synced back and forth. I would like to avoid running a cluster if I can. Please tell me if I am misguided.
