DBT to process S3 data and write to GCS bucket

Hi Team,
I am trying to read data from S3 bucket(HUDI Tables) and write transformed data to GCS storage. I am unable to write output to GCS bucket. I have all permissions in place and used below configs at Thrift server. dbt is defaulting output to S3a bucket and writing output data to AWS S3 and not GCP.
looking for some guidance here from experts. Thanks in advance
