ref: https://stackoverflow.com/questions/52428679/how-to-remove-classes-from-subclasses

tested this approach should work. Code snippet:

from apache_beam.options.pipeline_options import PipelineOptions

class PipelineOptionTest:
  class UserDefinedOptions(PipelineOptions):
    @classmethod
    def _add_argparse_args(cls, parser):
      parser.add_value_provider_argument('--gcs_location')

  @classmethod
  def setUpClass(cls):
    cls.UserDefinedOptions = PipelineOptionTest.UserDefinedOptions

  def tearDown(self):
    # Unset the option added in setupClass to avoid interfere with other tests
    del PipelineOptionTest.UserDefinedOptions
    import gc
    gc.collect()

  def run(self):
    print(PipelineOptions.__subclasses__())
    x = PipelineOptions().get_all_options()
    print(x)

if __name__ == '__main__':
  test_instance = PipelineOptionTest()
  test_instance.setUpClass()
  test_instance.run()
  test_instance.tearDown()
  test_instance.run()

output:

{'runner': None, ... 's3_region_name': None, 's3_api_version': None, 's3_verify': None, 's3_disable_ssl': False, 'gcs_location': <apache_beam.options.value_provider.RuntimeValueProvider object at 0x1288d3c70>}
{'runner': None, ... 's3_region_name': None, 's3_api_version': None, 's3_verify': None, 's3_disable_ssl': False}

as can be seen the second run there is no longer --gcs_location
