Is it possible to pass configuration values to the CKEditor, e.g. to include a webspellchecker?

It’s possible, but [webspellchecker]
(https://ckeditor.com/docs/ckeditor5/latest/features/spelling-and-grammar-checking.html) is not free. So it’s not included.

We’ve got a License. The previous CKEditor Addon had the possibility to pass configuration parameters to the editor. In CKEditor 5 it would

ClassicEditor
    .create( editorElement, {
        plugins: [ ..., WProofreader ]
,
        wproofreader: {
            serviceProtocol: 'https',
            serviceHost: 'localhost',
            servicePort: '2880',
            servicePath: '/',
            srcUrl: 'https://host_name/virtual_directory/wscbundle/wscbundle.js'
        }
    } )

How could i pass the settings to the editor?

Not supported currently.

Okay

New updates:
From version 2.0.0, configuration on spell checker is available.
You could do it like below.

Config config = new Config();
config.setWproofReaderCloud();//For cloud server
config.setWproofReaderServer();//For self hosted server
VaadinCKEditor classicEditor = new VaadinCKEditorBuilder().with(builder -> {
  builder.config = config;
}).createVaadinCKEditor();
