Hi @GillaMadhukar-4663,
AFAIK, the expected feature is currently not supported. Update Agent Readiness is based on the hybrid runbook worker (HRW) being available so if the hybrid runbook worker (HRW) heartbeat data is available in Azure Monitor then it would have been possible but AFAIK it's current not supported.
Here is a similar question that's recently asked. It has the link to related feature request. If interested, you may upvote it.
