Is it possible to make the enemy minions push while I still farm?

I feel like I should improve my control over the minion waves and one thing that I always wished to do when the opponent isn't in the lane is to farm without having to push and be vulnerable to ganks. I try to freeze by last-hitting at the very last moment but this still keeps pushing the wave slowly to the enemy tower, so I mostly decide to push all the way to their tower and do a camp in the jungle.
