Is there any other way to restart my iPad
How can I reset my iPad using my iPhone
iPhone 11, iOS 15
Question marked as
There is no option to do that.
If your iPhone or iPad has iOS 15.2 or later installed, see: How to reset your iPhone, iPad, or iPod touch when you forgot your passcode - Apple Support
If that option is not available, you will need to use a computer. See: If you forgot your iPad passcode - Apple Support
See the following from that support article:
If you don't have a computer and you can't borrow one, you need to go to an Apple Store or Apple Authorized Service Provider for help.
