control rc car bidirectional dc motor

Hi,
I have a cheap rc car with two buttons frontward/backward(cost 2$), I need to use the board to control the car motor using arduino in safe way, can someone please guide me if it’s possible?
the photo of circuit is attached.

You probably need to better explain the button controller setup. You might use a small servo to push the buttons, or use two relays in place of the buttons like below.

thanks for your reply, i'm still a beginner and if there is a way to use the current board setup, or just small modification (e.g. adding diodes). what do you think?
