The examples with await foreach do not show if ConfigureAwait can be used.

It does make sense, and it can be used. But because the underlying tasks returned from MoveNextAsync and DisposeAsync aren't directly available, you employ ConfigureAwait using the ConfigureAwait extension method on IAsyncEnumerable<T>:
https://github.com/dotnet/corefx/blob/f9c848d6ad5415c1fa844f5403ea8ef78c408f9a/src/System.Threading.Tasks/ref/System.Threading.Tasks.cs#L78
e.g.
C#
await foreach (var item in source.ConfigureAwait(false))
{
...
}
