Sure.

internal class ArticleViewModel : BindableBase
{
    public ArticleViewModel()
    {
        SubmitCommandWithMethodGroup = new DelegateCommand<object>( SomeAsyncMethod );
        SubmitCommandWithLambda = new DelegateCommand<object>( async x => { var y = await Something(x); await SomethingElse(y); } );
    }

    public DelegateCommand<object> SubmitCommandWithMethodGroup { get; }
    public DelegateCommand<object> SubmitCommandWithLambda { get; }
}
