Is it possible to create an automated PWA installation with user's consent?

Question

I have a web app and have built a respective Electron app for Windows. I want to do the same thing for both IOS and Android without dealing with stores. The app is fully web but it will be hosted only locally, both front-end and back-end. So every client will have its own server in its own intranet.

The problem is that I do not want to open the local IP in every client browser and do 'Add to homescreen' manually.

The ideal approach would be to have an automated way to create and install the PWA on various local IOS, Android devices just as you would install an application in Windows.

My question: Is it possible to automatically create a PWA without having to go through the manual 'Browser' way?
