[Theme: Choco] How to remove the Comment bar for just one sticky post?

Hey there, I just migrated my blog to a self hosted www.remarpro.com environment: https://www.chrisontour84.de/

In the top, you will see a sticky post, showing a map of my current location and my latest video. Now I want to remove this line, but ONLY for this post and not for any other:

“Posted by Chris on 7th January 2016 in Travel Leave a Comment”

I basically want to remove the text and also the box, trying to make the sticky post less space consuming.

I found a lot of how tos to remove it for all posts, maybe you can help me how to do it with just that one single post?

Thanks ??
Chris
