3756366 - SAP Signavio Process Intelligence - BigQuery Connector - Option service account

Is there an option to configure the BigQuery connector using service account attached to the virtual machine. Or does the standard connection has the ability to connect using service account? 

Process Intelligence only supports the authentication combination of project id and service key.

The vm credentials are also inherently located on the customers vm, so Signavio would have not have access to them, making it technically impossible.
