Yes. Conveniently, Luffy used his most exhausting form while restricting the usage of any advanced Haki, limiting it to his last punch, which flattened Kizaru. I wonder what would have happened, if Luffy did the same as vs Kaido; using hours of internal destruction, barrier and ACoC while going through all of his forms, from gear stacking (Roc moves), Snakeman, boundman and G5. Rather than conveniently using the form of Snakeman that fought Katakuri..
