You can use the following code:

pipeline_run_config = get_current_pipeline_run_config()

# Create a StartUpdate object from the pipeline run configuration
start_update = StartUpdate.from_dict(pipeline_run_config)

# Check if the pipeline run is a full refresh
if start_update.full_refresh:
    print("The pipeline is running in Full Refresh mode.")
else:
    print("The pipeline is running in Incremental mode.")
