Hi Jeske818,
Welcome to Apple Support Communities. We understand that you're having an issue with disabling VoiceOver on your iPhone. We'd like to help you with this.
Since you're unable to use Siri to disable this, you can try to use one of these other steps:
Use accessibility shortcuts on iPhone:
- Triple-click the side button (on an iPhone with Face ID).
- Triple-click the Home button (on an iPhone with a Home button).
- Use Control Center.
- Go to Settings > Accessibility > VoiceOver, then turn the setting on or off.
Do any of those steps help? Let us know.
Have a good day.
