Pretty simple, and was an achievement in F1 2019 as well.
You have to win a race in either My Team or Driver Career.
Once you have won a race, back out to the main menu, and check your mailbox. In your mail box you should have received the trophy of the race you have won.
Click on the left thumb stick and go into 'Super Licence', once there, go to 'Trophy Cabinet' and select the trophy you want displaced.
Achievement will pop straight after
Hope this helped!:)
