Shiva's 112 ways to attain enlightenment and Buddha's way

I recently came across a video of a guru (https://www.youtube.com/watch?v=GPINIZmQDwI&t=1s) claiming that Buddha's method to enlightenment was just one of 112 methods discovered by Shiva many years before the time of Buddha. ( https://yogitonics.com/shivas-112-ways-to-attain-enlightenment/) . I was wondering if anyone knows if this is a valid claim. Are there other ways out there to attain enlightenment or is the eight-fold path the only way?
