How to remove labels on google earth map

I have spent several hours trying to figure out how to remove the point label in my google earth map. But I have not been successful.

The point lable is covering the important details of the plot and I will like to remove it.

Please how can I complete this task.

Secondly, is there a way to include start and end location on the map?

Longitude = output(:,2);
Latitude = output(:,1);

filename = 'Plotmap.kml';
lookAt.Range = 1500;
lookAt.Heading = 260;
kmlwritepoint(filename,Latitude, Longitude,alt,'LookAt',lookAt);
winopen(filename)
