Hello
Thank you for posting your query in the Microsoft Q&A Community.
Please be informed that users who have the "Virtual Machine Administrator Login" role assigned can sign in to an Azure virtual machine with administrator privileges on that particular machine and are not able to manage other parts of the resource.
When you deploy a Virtual machine, other resources like the NIC are deployed separately and are associated with the Network resource.
To provide comprehensive access, you might need to assign additional roles or permissions to allow this access like Virtual Machine Contributor and Network Contributor on the Resource group or create a custom role to include all the permissions needed.
Let me know if further assistance is needed.
