Disable popup "this network has no access to internet"

Hi, I'm developing an app that requires to connect to Wi-Fi hotspot to pair an Iot device. Often, while IPhone is connected to the device's Wi-Fi hotspot, I get the annoying popup saying that the Wi-Fi network has not access to the internet , suggesting the user to switch back to another network/mobile data. This behavior may create problems with end users, that often taps on the button to switch the net, disconnecting from my device and failing pairing process/data exchange. Is there an option/permission to disable such behavior on my specific app or this is a system function? thanks a lot!
