NuGet plugin credential providers window is still visible

After NuGet.Client#2976 the credential providers windows is still visible.

In our solution we have a custom implementation of the PluginFactory class just to prevent the CredentialProvider.Microsoft.exe window being displayed and the only solution we have found that works is to add "CreateNoWindow = true" to the startInfo of the process. Would it be possible to add this parameter to the process, or make it easily configurable from the outside?

Thank you.
