Map has default "My Location" text how can I change it and get rid of nearby hotels and restaurants?

Hi,

Im making a map and Im using IsShowingUser to show where I am. If I tap my blue dot a default text pops up: "My location" I want to change this text but I'm not sure how. I can get rid of this text with isEnabled="false"

Also I was wondering if there is a way to hide nearby restaurants, hotels and museums on the map?

here is my map:
maps:Map WidthRequest="300" HeightRequest="300" Margin="5,10,5,10" x:Name="MyMap" MapType="Street" IsVisible="false" IsEnabled="false" IsShowingUser="true" HasZoomEnabled="true"
