Hello Balan Murugan,
Unfortunately, Azure Data Share does not directly support column selection (projection) during data sharing
As an alternatives:
You can ask the source team to create a view that includes only non-PII columns and share the view via Azure data share.
If Azure Data Share does not meet your requirements, you might explore other data-sharing options such as ADF, Synapse and Azure databricks.
I hope this answers your questions.
