$form = $this->createFormBuilder()
    ->add(child: 'SomeSelectField', type: ChoiceType::class, options: [
        'choices' => [
            'choice1' => 'value1',
            'choice1' => 'value2',
            'choice1' => 'value3'

    ->add(child: 'save', type: SubmitType::class, options: [
        'label' => 'Try me'
    ])

    ->addEventListener(
        FormEvents::PRE_SUBMIT,
        function (PreSubmitEvent $event): void {

            // fetch submitted value
            $data = $event->getData()['SomeSelectField']; 

            $form = $event->getForm();

            // retrieve original select field options, so we won't need to repeat them
            $opts = $form->get('SomeSelectField')->getConfig()->getOptions();  

            // here we're adding our fetched submitted value to the list of select field options
            $opts['choices'][$data] = $data;

            // not sure if this is needed, but i like to leave it for clearity
            $form->remove('SomeSelectField');

            // add reconfigured (=with changed options) field
            $form->add(child: 'SomeSelectField', type: ChoiceType::class, options: $opts);
        }
    )

    ->getForm();
