@Arif Usman Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
To mount a file share, you must use SMB. SMB supports mounting the file share using Identity based authentication (AD DS and AAD DS) or storage account key (not SAS). SAS key can only be used when accessing the file share using REST (for example, Storage Explorer).
This is covered in the FAQ: Frequently asked questions (FAQ) for Azure Files | Microsoft Learn
But we have workaround for this here I haven't tried in my lab.
Please let us know if you have any further queries. I’m happy to assist you further.
