You should be able to update your iPhone 7 Plus to the latest release of iOS 15.

You cannot update your iPhone 7 Plus to iOS 16 or higher, if that is what you are really asking about. For your phone, iOS 15 is the end of the line. If you need a newer version of iOS, you will need to buy a new iPhone.
