It could. Law has shown a lot of expertise with his fruit, but with the new revelation that Devil Fruits have an entirely new level of power with Awakening, its hard to know where to put a technique like that. In other words, due to the level of the technique, its hard to say whether or not that it's something that would require awakening. The Ope Ope No Mi has been shown to have some ridiculous abilities, some would even call it overpowered. The ability to give someone eternal life however, seems like its in a tier of its own compared to everything else we've seen so of it so far.

On the other hand, Doflamingo seemed a little too gung-ho about the user readily sacrificing themselves for him. As someone who knows firsthand what goes into awakening your fruit, I'd imagine he wouldn't take it lightly. Raising a pig for slaughter is one thing, but that's a pretty serious investment to make sure the person awakens the fruit as well. The only reason I bring this up is because I'm entertaining the idea that he DOESN'T know how to do it. Using it once would kill him, so its not like he's done it before, or can even "practice" it. If he truly has no interest in it whatsoever, then there never would have been a reason for him to have to learn it. So wow, I actually find myself unsure here when I thought a question like this would be a simple yes or no lol. I'm leaning more toward a yes though.

Long story short, I'm about 60% sure he knows how to do it. The ability is specifically unique to the Ope Ope No Mi, but at the same time I feel it's foolhardy to just assume that the user would instinctively know how to do it. Since it kills the user its not something that can be practiced until perfected like most Devil Fruit abilities. Awkakening might not be required, but at the same time I do think a certain level mastery of the fruit is, which Law may or may not be at currently. The main reason I lean more toward him actually knowing how to do it: If he DOES know already, then it makes plenty of sense why he'd choose to not use it up until now. If he DOESN'T know how to do it, I'm not exactly sure how he's supposed to "learn". In either case Oda brought the ability up for a reason, so if we don't eventually see Law use it, I'm sure will be given historical context on someone who has.
