Percussion Technique confusion at end of score

Here is a snippet of a last measure in a percussion score. I am trying to add a specific playing technique, and it seems to be cut off.

Is the playing technique the 18" Cym Ens? This is perhaps a dumb question, but can’t you adjust it in Engrave mode?

Unfortunately the way Dorico draws these overlays means that they won’t draw beyond the edge of the page. You could temporarily add an extra bar to the end of your flow and then remove it again if this is proving to be a real obstacle.
