Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
To address your query,
- No
- Azure Traffic Manager cannot be used in this scenario, at least, not the standalone one.
- Please refer : Azure VPN with Azure Traffic Manager
However, I am not sure why you would like to use ATM when you have a vWAN.
- See : Disaster recovery design vWAN
- For P2S users, you can consider using a global profile for User VPN clients
- This creates a P2S Configuration which consists of all the P2S Gateways of the vWAN
- Virtual WAN has a built-in traffic manager that selects the best hub for remote user connectivity automatically
- For a S2S, You can consider Multi-region multi-link topology
- Basically, you setup a primary connection to the OnPrem's regions, and a secondary connection to the OnPrem's failover region
Hope this helps.
Please let us know if we can be of any further assistance here.
