iOS 15.8.3 is the highest an iPhone 7 Plus can be updated to. It lacks the hardware to be updated any higher. If you need higher level iOS versions, then you'll have buy a much newer, more modern iPhone.
The iPhone 7 Plus originally ran iOS 10. You can update it to the latest version of iOS 15 (currently 15.8.3).
