How to call a request and implement the functionality of disabling WiFi for a site visitor?

Question

Mobile development

Good evening, dear experts!
Situation:
A user accesses a site or a specific section of a site from a mobile device (IOS or Android) using WiFi for connection. Is it possible to automatically show him a pop-up window with the following content: "Our site is not available on WiFi blah blah ... Click "Yes" to turn off WiFi on your device." When you press the WiFi button on the device, it should automatically turn off.
It is clear that it is not a problem to determine the operating system and display a push window, but what about disabling WiFi on a click?
Is it possible to implement this functionality? If yes, then they are ready to pay for consultation and development.
Thanks for the replies and your time!
PS The example in the text is given "purely for an example". Interested in a much wider application. Including and vice versa, not turning off WiFi, but turning it on for heavy pages or when advertising heavy mobile applications.

very interesting site ...
Now everything works on Wi-Fi, mobile Internet is not rubber and not cheap in general.
It's like saying that our site does not work over the Internet.
no way

Google there is a way to determine the provider by ip on the server.
If the user is not through a mobile operator, then we notify.
It is impossible to disable wifi on the user's device and I think it will never be possible.
