    In posted link it is written that fingerprint memory cannot be accessible outside internal Trused Area. This is a security reason. So the sensor cannot be used outside that Protected/Trusted Area. – emandt Apr 15 '21 at 17:48

The answer is NO. Fingerprints are highly confidential and Android does not allow users data or any form of processed or raw fingerprint data to leave the trusted environment (Mobile hardware). for more information you can read about Fingerprint HIDL.
