Update ios 17.4.1.why I cannot update my iphone’s ios?

Is your tag line correct that you own an iPhone X? If it is, iPhone X is not capable of being updated to iOS 17 at all. If you own a newer model iPhone than X and you are having an issue, please describe what happens when you try.

Hey! How are you doing? As shown in the iOS 17 Compatibility Guide, you must have an iPhone XR or newer to experience and use the iOS 17. I would recommend you buying a new iPhone, as there is no way you could access iOS 17 with your iPhone X.
