I am upgrading ES to the latest version, but after installing it, I found that some of the pipelines I don't need but I cannot delete them,
logs@json-pipeline
logs-default-pipeline
logs@json-message
ent-search-generic-ingestion
search-default-ingestion
behavioral_analytics-events-final_pipeline
logs@default-pipeline
When I deleted them and restarted the ES service, the following log appeared and they were added back

May I ask how I should handle it
