Huawei Mate 10 Lite Network Search Issue: How to Disable No Signal in Manual Search Popup?

I have a problem with my phone. Namely, I live in a place where it is not very good range. Setting the manual network selection is an obvious matter, but not for the phone which after losing the selected network displays the "no signal in manual search" window which prevents normal operation on the phone until one of the options is selected - "connect to the previously used network "and" search for new networks ". Selecting any option leads to network selection, and since the preferred network does not have the phone "forces me" to connect to the unwanted network. Is there any way to turn off this box? (also adds a screen with a window)

It would be best to amplify the signal in a place where this range is low or very weak.
As for the message, look in the network settings maybe there are some additional options.

As so, it's easier to enable in the "connect via Wi-Fi" settings, who would still be playing with some antennas today. The Wi-Fi calling service is just created for this, after the screenshot I see that you are on the Play network, look here https://www.play.pl/uslugi/wifi-calling/. I suspect that the message about the lack of network will disappear by itself as it will be possible to switch to Wi-Fi.
