How to give Sharepoint folder granular access to a Service Principal

Our team is working to get data from Sharepoint to Azure blob storage. We decided to use ADF as logic apps has size limitations.

The doc referred is https://docs.microsoft.com/en-us/azure/data-factory/connector-sharepoint-online-list?tabs=data-factory

To complete this solution, we need to give the sharepoint site full access to the application registered from azure portal. ("https://[your_site_url]/_layouts/15/http://appinv.aspx/")

However, there are some folders with restricted content which we don't want to give access to (app).

So is there any way to give the app access to only specific folders in the sharepoint site ?
