Hi Kaniz,

Thanks for the reply.

Yes. This is exactly what I am looking for.

"It appears that you’re trying to configure the runtime_engine in Databricks cluster policy using JSON. The PHOTON option is getting enabled but greyed out, and you’d like to know how to prevent that. Let’s dive into this!"

I don't want it to be grayed out.. I just want it to be checked and accessible...

I used standard Databricks Runtime (11.3 LTS (Scala 2.12, Spark 3.3.0)).

Is there anything other than type=fixed, so that it won't gray out.
