I'm sure it's possible. And I doubt you can find any guides in how to play like that, as that sounds unbelievably boring and niche, in a game that is not remotely designed to be played like that. Just be very selective in the quests you take, and kill a billion NPC's you think might be evil. Or gather a trillion herbs and/or ores to level up, like that Pandaren did in the Pandaren starter zone to level up to max level, or something ludicrous like that.
