Read-only repository for NON-object storage

[RubinCompServ]

I know, use, and love Veeam's Object Storage Read-Only Mode. Are there any plans to do the same thing for non-object storage (i.e. Linux-based repository)? Not all of our backups go to S3, but all of our backups do go to a regular repository, and we'd love to be able to take advantage of the "clean room" capabilities of read-only mounting to a different VBR.
