You’re likely not going to find a premade dashboard that does exactly what you want, but grafana is extremely powerful if you’re willing to put in the time to learn it. There are ways to visualize things across hosts without having to configure things separately for every host. If you’re using the same mechanism to scrape metrics from each (sounds like you’re using prometheus + node exporter?), this could be as simple as adding a by (node) (or whatever the label name is if it’s not node) grouping to the query on each panel.
