You can extract, sign and ship the native libraries separately to the JAR, and/or extract, sign and repackage the JAR itself. Even if you load the libraries separately, the notarization process may still complain about the libraries in the JAR even if they're not loaded from there.
This way you can sign everything with your signature, and the hardened runtime and entitlements your application needs.
Best wishes,
Neil
