By having a Compatible Device:

See my User Tip: Use an iPhone 12, that is using 5G in order to update over Cellular - User Tip

IMPORTANT: If you have an option to update, however, then be certain you backup your iPhone first. That way, you will have something to restore your iPhone from should anything go wrong with the update

You have an iPhone XR. You must use a Wi-Fi Network or a computer that is connected to the internet to update your iPhone.

You can't. Wi-Fi is a requirement.
