Microsoft Graph /identity/identityProviders behavior in GCC High and DoD when API is documented as unsupported

Hello Microsoft team,

The Microsoft Graph documentation states that the /identity/identityProviders API is not supported in US Government GCC High (L4) and DoD (L5). List identityProviders API availability matrix confirms this. [learn.microsoft.com]

Can Microsoft confirm the expected behavior for an authenticated request to:

https://graph.microsoft.us/v1.0/identity/identityProviders

https://dod-graph.microsoft.us/v1.0/identity/identityProviders

Specifically:

Should clients expect HTTP 404?

If yes, what is the expected Graph error.code (for example, Request_ResourceNotFound)?

If not, what is the documented status code and error payload?

We are implementing cloud-specific handling and would like to rely on documented Microsoft behavior rather than assumptions.

Thank you.Hello Microsoft team,
