Hi @noorbasha534 ,
To restrict developers from selecting Photon in job clusters, you need to define a cluster policy that enforces constraints on the "runtime_engine" field.
{
"runtime_engine": {
"type": "fixed",
"value": "STANDARD",
"hidden": true
}
}
•The "type": "fixed" ensures that users cannot modify this value.
• The "value": "STANDARD" forces clusters to only use the Standard runtime, effectively blocking Photon.
•The "hidden": true prevents developers from even seeing this option in the UI.
“I created a new policy called ‘test’ to verify the restrictions, and as you can see, the option doesn’t appear in the menu! 🙂 “ (Without hidden It will appear but you cant select it)

Hope this helps 🙂
