[V13] Is the "Block Generation" registry setting from KB4470 still functional?

[matsusan]

I have a question about the registry setting "ObjectStorageImmutabilityGenerationDays" described in KB4470.
The article mentions that for Veeam Backup & Replication v13, it is no longer recommended to change the block generation settings
due to improvements in handling immutability API calls.

However, I would like to confirm if this registry setting is still technically functional and configurable in v13.
My goal is to understand if the setting can be applied, even if it is not a recommended.

Thanks,
Ryoma
