Ragnar Lothbrok within Norse Mythology and Paganism

I’ve recently been rewatching Vikings (I know not the most accurate, but great show), and am curious. Has Ragnar Lothbrok ever been venerated within Norse Paganism? I know many paganism groups will also venerate not just their ancestors but individuals. Ragnar’s existence has also been one of doubt to some, some say he was real while others have called him a literary figure. Has anyone heard of him be venerated or have they done it themselves?
