Hello Monisa Magudeswaran
If you require architectural guidance for deploying the NVA product in an Azure environment, you can contact the Professional Direct support plan.
Azure Professional Direct (ProDirect) Support offers a premium support plan with faster response times, architecture guidance, and ProDirect delivery managers to help with your Azure solutions.
Refer: - https://azure.microsoft.com/en-us/support/plans/prodirect/
Additionally, you can consider contacting sales : Contact Microsoft Azure Sales
- You may either chat with them or call them via regional phone numbers, explain your requirement so that they will be able to share the appropriate details, support plan or direct Cloud Solution Architect engagement.
Ideally, it should be either "PROFESSIONAL DIRECT" or "UNIFIED ENTERPRISE"
Once you connect with the Sales agent, they will align you with an Azure certified partner who can address your queries.
I hope this has been helpful!
