Resource Owner Password (with realm) through Auth0 with AzureAD (Enterprise connection)

I am working on a POC to verify if it is possible to get a token using a POST request of type “Resource Owner Password (with realm)” and specifying in realm enterprise connection to check the user in AzureAD.

We have an ASP.NET app utilizes auth0 which provides login with AzureAD and our custom database connection. We have also ASP.NET Core API that is using token from auth0 (Resource Owner Password (with realm)) and we want to add support for AzureAD. Currently, if the client wants to utilize the API needs to be in our database and send a request to auth for the token. We want to extend it to support users from Azure AD.

Is it possible at all? Is it possible without prompting any login page?

Thanks for any help,
