Hi @Scott Klein ,
Thanks for contacting Microsoft Q&A.
Azure Security Center has security policies that can be set at various scopes, including subscription, resource group, and individual resource (e.g., VM). These policies can enforce certain security configurations, and they may override your manual settings. Here's what you can do:
a. Check Azure Security Center Policies: Go to the Azure Security Center in the Azure portal and review your security policies. Ensure that there are no policies at the subscription or resource group level that are automatically enabling Microsoft Defender for Servers.
b. Modify or Disable Policies: If you find policies that are affecting your VMs, you can modify or disable them as needed to prevent automatic re-enabling of Microsoft Defender for Servers.
Hope this helps you.
