Map settings, street names, and map alerts

Hi !

I have several questions:
First, I have seen some pictures with fenix 5X plus with maps without street names. I don't care about street names and find that more readable to have only segments and no names on the watch during an activity. However, I haven't found a way to disable street names. How can I do that ?
Also, I would like to have data screen during my runs, and have alerts showing me the map several seconds when I need to turn. I know it's possible as I used to have that but I desactivated it somehow and cannot find a way to put it back on. Does anyone know ?
And, does anyone know if the fenix 3 built in digital watch face is installable on the fenix 5X plus, and if it would drain more battery ?

Thanks a lot !

Clément.
