You can easely farm any badges with the following configuration :

I recommend the following if you want JUST this achievement : Bronze Race Wins : Choose the fastest car you have (the fastest in the game are Bugatti Veyron, 2011 Koenigsegg, 2017 Ford GT) and set 1 drivatar and 1 laps long in order to do the quickest race (about 1 min). Finish it first and Restart it over and over in order to get the Platine Badge. Of course you can set the difficulty to the easiest level.
When you obtained your badge, just go on the main menu => Pilote History => Change Badge => Select the badge
