Info Window/Templates Customization

Hello, I am a new french user of your great plugin.

Is it possible to customize the info Window placemark for not using the sticky image and does not display the information content, but rather just the address and a website?

In addition, it is possible to display only one corresponding marker has a placemark (not with the shortcode, but modifying the query and by creating new page templates (eg single-placemark.php, archive-placemark. php, category-aplacemark.php)

Thank you in advance for your response.
bests regards
