Hello, It's not possible directly.
One possible workaround that comes to mind is using snapshots. You could take periodic snapshots of the Prometheus database and flush them to the filesystem at a lower frequency, say every 5 minutes, as you mentioned. Then you can sync the snapshot to disk. Note: You can decide to snapshot the head or just the blocks.
