Sure. I've used it to add a bit of fruit and punch to a Smash (Gascon Smash), to modify a Martini (Plum Blossom Martini), in a Fizz (a variation on Toby Maloney’s Williams Fizz), a Dark & Stormy variation (Alastair Burgess' Perfect Storm), etc.
Death & Co has a few recipes that use a touch of eau-de-vie as an ingredient to add flavor without adding sweetness.
