The only setting that matters for this achievement is the quarter length. 5 minute quarters are minimum for this achievement.
Other then that, you can turn off all NBA rules, and turn User/Computer Sliders up/down.
A triple double is double digits in 3 of the 5 categories ( Points, Assists, Rebounds, Blocks, Steals)
With sliders up, the easiest way would be 10 points, 10 assists, 10 steals.
Steal the ball, score. repeat 5 times. Steal the ball another 10 times and pass it off to someone else and make the shot with them. Repeat until you have 10 points, assists and steals.
