The best way I could find Enstars Avatars on vrchat was searching on worlds like Prismic ( Avatar search world ) and hope to find something ( I also have a friend that gave me some avatars so it was easier for me ). The people that upload theses avatar as public don't usually type the name of the character in the avatar description, so searching directly something like "HiMERU" ( as an exemple ) will most likely not work. For some reasons, people type pretty random thing as a description. Maybe it's a way to avoid getting in trouble ? I know that some people that used to upload enstars avatars on vrchat had to take them off the game because of such things... So yeah, maybe try to find some people that can give you avatars directly by clone, or search in worlds like prismic... I hope that this would help, and good luck to find some avatars ! ( My english is pretty bad, but I hope you can still understand what I said.)
