Is there a way to set the Prefect Run Configuration default in the UI? Of not, how do I do it on registration. I need to specify a Local config rather than Universal for some jobs.

You can’t set the default through the UI, but you can set it for an adhoc run. Flow the flow, it just becomes:

from prefect.run_configs import LocalRun
flow.run_config = LocalRun(...)

so like this

with Flow(
    "Project Git/SDK Version",
    # executor=LocalDaskExecutor(),
    state_handlers=[psh.flow_failure],
    executor=LocalExecutor(),
    # result=GCSResult(bucket="platformsh-vendor-prefect"),
) as flow:
    project_ids = list_elite_projects()
    info = fetch_system_info.map(project_ids)
    flat_data = flatten_json(flatten(info), "platform")
    schema = generate_schema(flat_data)
    object_uri = upload_gcs(flat_data, "project", "project_system")
    status = gcs_to_bq(
        object_uri,
        "project_system",
        dataset="GCP_PLATFORMAPI_DATASET",
        schema=schema,
    )
flow.run_config = LocalRun()
