Hello,
The answer can be found below (answer from SumanthMarigowda-MSFT):
By default, standard file shares can span only up to 5 TiB, although the share limit can be increased to 100 TiB. To do this, large file share feature must be enabled at the storage account-level. Premium storage accounts (FileStorage storage accounts) don't have the large file share feature flag as all premium file shares are already enabled for provisioning up to the full 100 TiB capacity.
You can only enable large file shares on locally redundant or zone redundant standard storage accounts. Once you have enabled the large file share feature flag, you can't change the redundancy level to geo-redundant or geo-zone-redundant storage.
To enable large file shares on an existing storage account, navigate to the Configuration view in the storage account's table of contents, and switch the large file share rocker switch to enabled:

You can also enable 100 TiB file shares through the Set-AzStorageAccount PowerShell cmdlet and the az storage account update Azure CLI command.
