How To Manage Looker Dashboards Across The Organization

my company has been using Looker extensively across teams for monitoring, analysis, reporting purposes for a decade. One problem we face is people may build looks or dashboards without being aware that something similar already exists. So it ends up we have thousands of looks/dashboards in the infrastructure which is very unnecessary.

We want to come up with a solution to organize the Looker structure better and clean up duplicated visualizations. But we are also aware that it is very hard to depend on the users for this…

Is it possible to use the Looker API to check the content of looks/dashboards and delete duplications? Or are there other solutions?

Thanks in advance!
