I am trying to access the fingerprint photo access from the in-display fingerprint sensor for a specific use case. Is it possible to do so?

For privacy reasons fingerprints images can never be accessed by Android apps. The following text is about Google Nexus/Pixel phones, but as far as I know it also applies to phones of other manufacturer:
Your fingerprint data is stored securely and never leaves your Pixel or Nexus phone. Your fingerprint data isn't shared with Google or any apps on your device. Apps are notified only whether your fingerprint was verified.

The reader is only usable by Android itself for authentication.
As an app developer you can only ask Android to perform an authentication and in the end get the result (success/failure).
