Are there options for access permissions and symlinks?

Is it possible to set mountOpions permissions as it is done with

```
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: azurefile-csi-smb
provisioner: file.csi.azure.com
parameters:
  protocol: smb
  skuName: Standard_LRS
**mountOptions:
  - dir_mode=0777
  - file_mode=0777
  - serverino
  - mfsymlinks # This option enables symbolic link support for SMB**

```
