Fuses are there on all phones since 25+ years ago, on the real phone CPU side. With trusted boot and shit. Otherwise you could change IMEI left and right and it's a big no-no. What you interact with runs on the secondary CPU -- the fancy user interface with shiny buttons, but that firmware only starts if the main one lets it.

You can still change the IMEI on many phones if you know how to.
