How to configure Glue Connection to successfuly connect to Oracle RDS Using NNE (Not SSL)

As part of our migration to AWS, we've created an Oracle RDS that is configured for Native Network Encryption.... No SSL

Oracle Option Group:

SQLNET.ALLOW_WEAK_CRYPTO	true
SQLNET.ALLOW_WEAK_CRYPTO_CLIENTS	true
SQLNET.CRYPTO_CHECKSUM_CLIENT	REQUESTED
SQLNET.CRYPTO_CHECKSUM_TYPES_CLIENT	SHA512, SHA384, SHA256
SQLNET.ENCRYPTION_CLIENT	REQUESTED
SQLNET.ENCRYPTION_TYPES_CLIENT	RC4_256, AES256, AES192, 3DES168, RC4_128, AES128, 3DES112, RC4_56, DES, RC4_40, DES40
SQLNET.ENCRYPTION_SERVER	REQUIRED
SQLNET.ENCRYPTION_TYPES_SERVER	AES256
SQLNET.CRYPTO_CHECKSUM_SERVER	REQUIRED
SQLNET.CRYPTO_CHECKSUM_TYPES_SERVER	SHA256

I've tried several different formatted JDBC URLs... without success... (Like adding ?crypto_checksum_client=required&crypto_checksum_types_client=sha256 to the JDBC URL)

DMS Seems to have no issues connecting, but I cannot get a successful glue connection test.

I have a PySpark Job that will need to connect back to the Oracle DB to run a quick query, but having issues connecting... all_pk_df = glue_context.read.format("jdbc")
.option("url", jdbc_url)
.option("dbtable", oracle_primary_keys_sql)
.option("user", user)
.option("password", password)
.option("driver", 'oracle.jdbc.driver.OracleDriver')
.load()

I've tried setting options in the Python code as well, but haven't found the correct property as of yet...

The issue seems to be with this: SQLNET.CRYPTO_CHECKSUM_TYPES_SERVER SHA256 as when it was SHA1, connection was possible...
