Cannot set unix permission for Azure NetApp File volumes during creation

[eyanghometrust]

Describe the solution you'd like
A clear and concise description of what you want to happen.
During our recent deployment of SAS Viya 4 using AKS, Azure NetApp File and trident provisioner for NFS volumes, we noticed that the pvc that was created by trident has a default permission of 770. SAS requires 777 on the mount point in order to install the application. But we noticed we are not able to set the unix permission in trident backend or storage class that uses trident as provisioner.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
The concern is that trident is not able to change the unix permission of mountpoint while it's creating pvc on Azure Netapp File.
We had to either change the permission to 777 manually after the pvc and mountpoint is created or using different NFS provisioner.
