@Xie, Tina Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

Presently, It's not possible for Azure File share,
Workaround: Last modified date is the only alternative that is available.
If you wish you may leave your feedback  here. All the feedback you share in these forums will be monitored and reviewed by the Microsoft engineering teams responsible for building Azure.

Additional information :
In general, if you want to track the last access time of the blob, you can enable the last access time tracking feature on the account level.
Optionally enable access time tracking

Once enabled, and you try to check the properties, this shall provide you the last access time of the blob.

Moving ahead, in order to track operation on the storage account, you can rely on the storage diagnostic logging. Since you will be using the SAS token, it won't be logging any user specific details and only log SAS as the authentication scheme. You can narrow down the search based on user agent, client IP and request URL (blob name).

Below is a sample blog for reference on the concept. You can apply the same approach to the newer diagnostic logging as well.
