I want people to be able to see my profile picture without feeling the need to like it and comment about it.
There is no way to disable the comments and likes for all friends. You can do it for specific people if want to do that. What you can do is change the profile picture and set the privacy setting to "Only Me". This way no of your friends will see the update on their Timeline, so there is no chance to like and comment until they do not click on your profile. Friends can it in the thumbnail profile picture.
