I want to update my iPhone to iOS 17.6?

An iPhone 6s, iPhone 6s Plus, iPhone 7, iPhone 7 Plus, or iPhone SE 1 isn't capable of 16 or above; they require an A11 or better CPU. To install 15.8.3, use a computer or the Software Update function in Settings.

The iPhone 7 cannot even run iOS 16, so there is no way that it could ever run iOS 17.

If you want to run iOS 17, you will need an iPhone XR or higher model.
