I’ll give you the non-sugar coated reality of that situation.
Right now, no there isn’t a way. The population isn’t large enough for the match making to have the ELO enabled again. However, once the winter update hits that will most likely change. Once the game has its “free to try” model that will definitely change.
On a related note, IMHO you shouldn’t even be looking into PvP until you’ve run through the story missions and leveled up a few toons to 10 or so. The reason being you won’t be able to really hold your own unless you really understand your toon and have at least 2 or 3 alternatives to play in the event someone picks your favorite/main. Not to mention, while you don’t need legendaries, you should have at least a few pieces of decent gear and a few load outs to accommodate the game mode you’re playing.
I’ve seen too many cases of newbies going into capture with load outs they’ll never get to activate. 3 zero cost or 2 zero cost with a really cheap green/purple is normally your best bet. I see some people with all purples and by the time they can activate one the game is almost done. Or some where new players are running no gear because they jumped right into PvP.
