Restoring Single Files/Directories from backup images

I have the files that need to be restored from a backup and normally we do two sets of backups, one through Proxmox and one via another program to S3. The S3 backups did not contain the data needed so I'm thinking our only option to restore the directory is in the Proxmox vma backup.

My question is, is it possible to mount externally or internally the vma to access the files?

Thanks.
