Thanks for the reply, but unfortunately this is not what I am looking for. I have already enabled automatic upgrades.

What I am specifically looking for is to change the image offer that vm scale set is referencing to.

@SagarShrestha To update the OS image in Virtual Machine scale set, for example if you have a scale set that runs an old version of Ubuntu LTS 16.04 and you want to update to a newer version of Ubuntu LTS 16.04, such as version 16.04.201801090
You can use the following Powershell command as per the doc shared below:

Update-AzureRmVmss -ResourceGroupName "myResourceGroup" -VMScaleSetName "myScaleSet" -ImageReferenceVersion 16.04.201801090

OR Azure CLI with az vmss update:

az vmss update --resource-group myResourceGroup --name myScaleSet --set virtualMachineProfile.storageProfile.imageReference.version=16.04.201801090

Please refer to How to Modify a virtual machine scale set doc for more details.
