Not that I know. But you can remove it with a bit of css.
Add this to conf/userstyle.css (create the file if needed)
div#dokuwiki__content div.pageId {
display: none;
}
Clear your browser cache and reload the page.
PS
Could you paste a link to just the image, not the full imgur site ? I did not watch GOT S08E05 yet and was almost spoiled by some kind of notes on the site.
