Leibniz denies the existence of causation in his Monadology[1]. In short, everything acts solely according to its own nature without any interaction with anything else, but in a harmonious way that creates the illusion of causation. That strikes me as a bit far fetched, but it does show that accepting the existence of causation is a metaphysical choice and not necessary.
> Leibniz denies the existence of causation in his Monadology
This sentence is incoherent unless one assumes the denial of causation is bunk, since it makes no sense to attribute either Monadology in general or the specific claims from it being discussed to Leibniz unless he caused the existence of the work, which clearly he cannot have if there is no causation.
