How to disable ion-toggle in a reactive form

In an Angular reactive form, how to disable an ion-toggle inside an item without disabling the item itself?

The disabled prop doesn’t do the job

<ion-item lines="none">
  <ion-toggle
    slot="start"
    enableOnOffLabels
    formControlName="orderMode"
    [disabled]="true"
  ></ion-toggle>
  <ion-label>
    something here
  </ion-label>
</ion-item>

form.get('orderMode')?.disable(); works but disables the entire ion-item
