How to remove these pipelines from ES8.17.5

Elastic Search
1

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
[2025-03-27T15:35:24,937][INFO ][o.e.x.c.t.IndexTemplateRegistry] [HKAPPDWV2003_node1] adding ingest pipeline logs@json-message

May I ask how I should handle it

Welcome to the forum.

You asked for suggestions - I suggest, based on what information you supplied, NOT to delete them.

Maybe better explain what actual problems they are creating for you?

By the way , I thought latest is currently 8.17.4? You really using 8.17.5?

Thanks for the clarification

So maybe one of the Elastic employees will reply with an official answer / way / advice.

Personally, within any product there’s features I might not personally be interested to use currently. But I can’t really appreciate the full interdependences between this and that across the whole product. So I’d be ultra-cautious before deleting stuff. Your pipelines and the system supplied pipelines can surely coexist.
