Velero: Unable to use a nested prefix, nor override it by setting it myself in values

[boatmisser]

Description

In the velero template there are a LOT of defaults populated via the set list.
One of these is the prefix which is taken from the s3_backup_location using a split on /.
This is coded to only take the first result, so any nested prefix is truncated e.g. 'foo/bar' becomes foo.
This would not be a problem except that I cannot override it by setting it myself in the values; it keeps creating it using the result of the split.
Can we either allow the prefix to be more than one level deep; or provide a way to override, or to switch off, the use of the set so I can do it myself.

I used to be able to do this in the previous version of blueprints v4.32.1 !

If your request is for a new feature, please use the Feature request template.
I don't consider this a feature request at this time as the blueprint should at the very least provide a method to override the default method of specifying the prefix.

Reproduction Code [Required]

enable_velero = true
  velero        = {
    s3_backup_location = "arn:aws:s3:::${data.aws_caller_identity.current.account_id}-software-platforms/foo/bar"
    values             = [templatefile("${path.module}/helm_values/velero.yaml", {
      prefix                    = "foo/bar"
    })]

velero.yaml

configuration:
  backupStorageLocation:
    prefix: ${prefix}

Result is always:

objectStorage:
    bucket: XXXXXXXXXXXX-software-platforms
    prefix: foo

Expect:

objectStorage:
    bucket: XXXXXXXXXXXX-software-platforms
    prefix: foo/bar

Steps to reproduce the behaviour:

Try to install velero with a nested prefix (i.e. a prefix containing a /); either via s3_backup_location or values.

Expected behaviour

Either the prefix should include my entire value e.g. foo/bar OR I should be able to override the generated prefix via the values OR have the ability to off the set entirely.

Actual behaviour

My prefix is stripped so I end up with foo instead of foo/bar AND I cannot override it via values.
