Hmm, just read the title and kinda skipped the 'nope', ;>. If it's what I think you wanna do, there's no way to do so AFAIK. Maybe there's a script for it within the thread linked in my edit, haven't tried them all. If you click that tiny eyeball next to the particular giveaway on the main page, you're able to hide them all for that game at least there.
EDIT:
Sry, strike that, SG Tags shows you a tag for hidden games, just didn't activate it.

"Ignored" tag means that you marked that game as not interested in Steam store
While "Hidden" tag are games that you hide in Steamgifts. Hidden tag only appears inside giveaway pages, usually useful for invite only giveaways.
Just as Tzaar commented below, you can hide games by clicking the eye icon next to the game title. You won't see that game anymore in giveaway listing, but you still can see them with invite only giveaways, that's why I make "Hidden" tag.
Here is where you can see your hidden list.

Would be especially useful for trains. Also, is there a way to nope a game, and maybe put a label for that, too, on the giveaway pages?
