Removing PLAY button on specific pages

Site URL: https://www.dougcook.ca

Hi there - wondering if anyone can help me out with removing the "Play" button on video thumbnails? I've been using this code which works perfect ... but it covers the entire site. I'm looking to remove the play button on specific pages and leave the play button on others.

Here is the code that I'm currently using: 

.collection-type-gallery .video-play-icon {
  display: none;
}

Add to Page Settings > Advanced > Header

<style>
  .collection-type-gallery .video-play-icon {
  display: none;
}
</style>

Works perfect! thank you very much!!!!
