Veeam Infrastructure Appliance: Supported Way to Expand Disks?

Hi


I am planning to deploy Veeam Backup & Replication v13 using the Veeam Infrastructure Appliance with a Hardened Repository configuration.
My question is about capacity expansion during production operation.
If the backup storage becomes insufficient after the appliance has been deployed and is already in use,
is it a supported operation to add an additional virtual disk to the appliance VM and expand the backup storage capacity (for example, extending the repository storage)?
Specifically, I would like to understand:

Whether adding a new virtual disk to the Veeam Infrastructure Appliance VM is officially supported
Whether this applies to a Hardened Repository configuration
If there are any restrictions, best practices, or unsupported scenarios we should be aware of

The goal is to increase backup capacity without redeploying the appliance.
If there is any official documentation or guidance from Veeam regarding this scenario, I would appreciate it.
Thank you in advance for your help.

Currently, this is not supported. I suggest to create a SOBR (https://helpcenter.veeam.com/docs/vbr/userguide/backup_repository_sobr.html?ver=13) from the beginning. 

If you need more storage, just deploy a new infrastrucutre appliance and add this storage to the SOBR.
