Hi @Philip Wesley , Thanks for posting your query on Microsoft Q&A.
Unfortunately, once you have created the VM template, you cannot change the size in Azure Lab services.
However, one alternative is to use Azure DevTest Labs, which supports changing the size of a lab virtual machine (VM), based on changing needs for CPU, network, or disk performance. This article describes how to resize a lab VM : Resize a lab VM in Azure DevTest Labs
While it is currently not possible to attach additional disks to a VM in a classroom lab in Azure Lab services, you can upvote the feature request on the Azure Lab Service feedback forum and elaborate your use case in the comments, so that Product group can prioritize it accordingly.
