As mentioned, after deploying pd_servers, tidb_servers, tikv_servers, and other monitoring services, and all these services can start normally, can additional components like tiflash be deployed at this time?

Got it. Just write a YAML file that only includes TiFlash, then use tiup cluster scale-out <cluster-name> xxx.yaml.
