Is it possible to permanently disable wifi anymore?

[riccinini]

Mine wifi keeps coming back on when I disable it.

How to permanently sotp it?

Have you actually disabled it by going to system settings > wifi or did you just "disconnect" it via control center by swiping from the top?

I use control center.

I can't actually find the settings app anymore. I deleted it I think?

No worries, it's impossible to get deleted.
You can search for "Wi-Fi" or "Settings":

Find settings on iPhone

In Settings on the iPhone Home Screen, find and change settings, such as your passcode, notification sounds, and more.

Or you could simply tell Siri do disable Wi-Fi.

edit: IMHO it's completely stupid this way when you already have Control Center for exactly this use case but apparently Apple thinks different...
