How to turn off featured image only for services

Hello, I'm sorry my english is very bad. I did a Google Translate translation ... I would only like to hide the featured image on the services page, but can't. The image must show the services on the home page but not in the header of the service page because the size is not suitable. When I try to deactivate in Adonis Pro Options -> Single Page / Post Image Layout it does not work. Thanks for your help. Laëtitia
