Yeah, it is, it's supposed to be canon despite how wacky and divisive it was

Also, the first live action movie is in a different timeline, though the time travelling villain in that movie shows up in other series with a different history, the second live action movie is only canon because it introduced a tiny transformation used in the later series, and gave Ben a car, also used in later series, and then the CGI movie is canon because an area that is damaged during the fight is colonized by alien life later on (according to the staff), becoming the underground city seen in Omniverse, sorry if this is a lot of info
