Can I update my phone anyway not using wifi

You need wifi or 5G (or a computer with wifi or Ethernet).

Use 5G with your iPhone

"Allow More Data on 5G: Enables higher data-usage features for apps and system tasks. These include higher-quality FaceTime, high-definition content on Apple TV, Apple Music songs and videos, and iOS updates over cellular."
