Hi,

Unfortunately, currently this theme doesn't support this feature. We will consider to add more this feature in the future updates.

Now, if you want to hide featured image for special posts, please add more this code to Customize >Custom CSS:

body.postid-250 .post-image{ display: none; }

Notes:

1/ Change value  250 on the above code to post ID of post you want to hide featured image. Check this guide to know how to find ID of a post.

2/ If you want to hide featured images for multiple posts, please use the code like this:

body.postid-250 .post-image,
body.postid-251 .post-image,
body.postid-252 .post-image,
body.postid-253 .post-image { display: none; }

Change values:  250, 251, 252, 253 for post IDs of posts you want to hide featured images.

Best Regards,

PenciDesign
