Is there any way I can turn off notifications of a specific post? I'd like to turn of notifications of one of my past posts since I keep receiving other people's conversations that are not relevant to my original question. I still want to keep receiving notifications of my other posts. 

This is what I see under the original question. Does this turn off only the notifications from this specific post? 
 

I also see this on the right side of the same post.

Do these two settings act in different ways?
