Get the previous to 20th version in grafana


I have been using grafana to track the incoming requests, HTTP status response, etc.

I was trying something and did the changes to the grafana dashboard and saving

Now I need to revert to the older versions of the dashboard but on default, it saves only the last 20. Do we have a way to get previous to 20 versions of grafana?

Please let me know if you need more information.
