Can't remove assist_pipeline or conversation integrations?

I wanted to try removing the following integrations from my home assistant instance: assist_pipeline, cloud, conversation, energy.

I removed default_config from my configuration.yaml and added back all the default integrations except those four.

The cloud and energy integrations went away as expected. However, assist_pipeline and conversation still seem to be there. The Voice assistants menu in Settings is still there unchanged, and the conversation services still show up.

Can we not actually remove assist_pipeline and conversation? Or is there something wrong on my end? I’m running Home Assistant OS, does that have something to do with it?

I have the same issue and no solution… something is broken

I found this unresolved post because I ran into this exact problem. Switched to removing default_config: from configuration.yaml. Added each integration manually. Commented out cloud, assist_pipeline, and conversation. Rebooted. Cloud was removed from settings. Individual entities still refers to voice assistant. Has anyone learned anything new about this?
