Hi @ARVIND S ,
Welcome to Microsoft Q&A! Thanks for posting the question.
I understand that you are looking for a solution which can do the manage operating system updates for your Windows and Linux virtual machines in Azure. I assume that by azure update management, you meant Azure Automation Update Management.
Please note that the Azure Automation Update Management does use the System Hybrid Runbook Worker and the installation of Update/patch is done through runbooks. It can also be used to manage OS updates for physical machines/VMs in on-premises environments and in other cloud environments. The following link gives a quick introduction and walkthough of the process -
Patch Azure Vms using Azure Update Management.
For more information, you may also refer to the official doc here - Azure Automation Update Management

Another option to manage patching, would be to use Automatic VM guest patching for Azure VMs. If automatic VM guest patching is enabled on a VM, then the available Critical and Security patches are downloaded and applied automatically on the VM. You may refer to this link for more details.
Hope it helps. In case the above answer does not help you, can you please share some additional context/details about the question to help us better understand it?
