Yes, instead of passing the options as command line arguments you can set them in the code.

After the following line:

pipeline_options = PipelineOptions(pipeline_args)

you can add the following 2 lines:

google_cloud_options = pipeline_options.view_as(GoogleCloudOptions)

google_cloud_options.temp_location = 'gs://tests_tmp/tmp'

You have to treat the options as GoogleCloudOptions, as PipelineOptions does not have temp_location attribute.

Here is the relevant part in the doc:
