No, not possible, node roles are defined in `elasticsearch.yml` and any change requires a restart of the node.

I am working on setting up SIEM, where I am getting logs in kibana.log saying.

so transform role is mandatory to setup SIEM is it correct?

```auto

It is not mandatory, your cluster will work without a Transform node, but some features will not work right.

I would recommend that you enable the transform role on one of your nodes.
