No sorry. The series is following the game timeline. Hence why you see leon belmonts portrait in the belmont home, and the story of leon searching for dracula/mathias after he disappeared and betrayed leon. Not only that but the characters hector and issac are in the sequel of the game that the anime is based off of. The series being based off of castlevania 3 and the sequel to 3 was curse of darkness which has hector and issac in it. The devil forgemasters. It seems season 3 will be based off of curse of darkness. Those hints you saw of the impaled bodies is something that Mathias did when he and leon belmont fought in the crusades together. A trait that he carried over as his new identity vlad tepes dracula.
