Other shooters it’s called aim assist, not auto target. I’m not if front of the game right now but generally aim assist is built right into most shooters on console and you can usually disable it. Though unless you are really good you are gonna have a bad time. Check your settings and look for something with that name. It may just be a sensitivity slider and not a toggle on/off as well. I’m sure it’s there because some people prefer to play that way.
sorry, i am actually on PC. but have checked both menu versions. because some options appear in the menu when using KB/M that do no appear when using gamepad. there doesn't seem to be any option for this anywhere. i have also checked files at the install and documents folder. there is a UserSettings file which has some options not in-game, but nothing changed removed this behavior.
in the end, it's not assisting in actual aim. again, it is just slowing down camera movement as the cross-hairs move past an enemy target. there's no auto-movement or sticky movement.
