Hi @Emma Harlow
In the current Update Management functionality, the feature to have Set or Disable cmdlet is not being invested or prioritized because investment or prioritization is on v2 (version2) of Update Management i.e., we are going to have "Update Management Center" as a separate Azure service which currently is in Private Preview stage and would be moving to Public Preview stage very soon (i.e., before the end of Q2 CY22). So, product team would be adding the feature to have Set or Disable cmdlet in that newer version.
