Deactivate GP Social Share in a post

I would personally disable the Hook and use the GP Hook Element to add the social share shortcode – then you can set the display rules to exclude it from that post.

Sorry, I hadn’t subscribed to forum posts and only just found out there were support requests, so my apologies.

As David said, you can use the built in GeneratePress Elements and the shortcode to disable/enable wherever you need it, alternatively you can hide on a single post using CSS

// replace postid-1 with the post id number for the post you want to hide it
body.postid-1 #gp-social-share {
display: none;
}
