The anti-seize is so the fuel filters don't gall with the threads of the filter base and become stuck.

That's what I figured , are you using an aftermarket adapter made from aluminum ? But isn't the threaded portion steel ? Also the threads on the filter aren't very deep/long so not much surface area to gall . Plus it lives in the fuel which is somewhat of a lubricant , have you had issues in the past removing the filter ?
I am not running an aftermarket filter on my Duramax but I struggled for a few fuel filter changes trying to unscrew the old filter . Then I got the idea to open the bleeder screw to relieve pressure . Since then no problems removing the filter . To answer your question no I would not apply anti seize .
