Isn't it easier just to go to settings->preferences->maps and just turn on or off the ones you want?
the preferences are saved in the browser, that is to say that each pc that enters must do the same, (each client) in the modern ui they are not saved in the server, so if I want, for example, only the bing map, I have to explain to each person how to see it, if I compile that modification it will remain in all users
Thats True - I misunderstood your question.
Try doing a text search for bing on the source-code - I guess you will find it
hello, thank you for your attention,
in the modern ui (compiling of course) what files should I modify if I wanted the 3 maps that appear at the beginning to be the ones I choose? example, remove carto and put bing?
