How do I delete unused boards which was historically created by users who have left Organisation?

I have multiple boards which is causing confusion. How do I delete unused boards which was historically created by users who have left the organization. Also, I do not have access to delete these boards as I have not been added as administrator. Thanks

You'll need help from an admin to do this. They can transfer ownership of the board's filter to you (or just delete it) and add you as a board admin, after which you should have permission to delete them.

Restricting the filter permissions could also be a way of limiting visibility, but again, you need an admin to make you the owner of the filter.
