@Dirk thanks. That’s how I did it but I am not sure if updating using docker compose would overwrite it. Portainer is running on a VM so I will make sure to snapshot it and try so I can restore it if needed.

@Catsrules Thanks. This specific to Immich. The upload location in the docker-compose is picked from .env file. I, for the life of me, cannot figure out how to mount the portainer SMB volume in the .env file. What I ended up doing was to select the containers using the upload location and edit the volume to attach the SMB share volume from portainer. I hope what I said makes sense. I am just a newbie learning docker right now.
