Authentication method for Bigquery as destination

Hi team ,

i am setting up bigquery as a destination in airbyte open source. i am processing sensitive data and i can’t use HMAC key as an authentication method for GCS staging (standard inserts is not a production option )
How can I set up the configuration using an alternative authentication method for GSC staging such as service account credentials or Tokens (oauth2) without using HMAC?

Thanks in advance.
