angular - Detect ngModelOptions in own component with ControlValueAccessor

Question

I would like to add a class to a component depending on the ngModelOptions setting.

component:

const INPUT_CONTROL_VALUE_ACCESSOR: ExistingProvider = {
    provide: NG_VALUE_ACCESSOR,
    useExisting: forwardRef(() => InputComponent),
    multi: true,
};

@Component({
    selector: 'my-input',
    templateUrl: 'input.component.html',
    providers: [ INPUT_CONTROL_VALUE_ACCESSOR ],
    changeDetection: ChangeDetectionStrategy.OnPush,
})
export class InputComponent implements ControlValueAccessor {

}

using:

<my-input [(ngModel)]="name"
    [ngModelOptions]="{ updateOn: 'blur' }"
    required
></cds-input>

How to check in my-input that updateOn: 'blur' has been set?

I tried @Input('ngModelOptions') but I feel it's wrong, and that won't work with FormControl.

is it possible to read AbstractControlOptions in some way?
