I did this on Pro Career. I took Red Bull Team. Max Verstappen as teammate. I skipped everything. I skipped Practice, Qualify and Retire from race ("Retire from session"). After round 6 / after race 6 (After Monaco) Your team is not happy with you and you are fired. You can now choose another team or retire. Of course choose the team you can pick and achievement is yours.
- you don't have to race at all.
- you need to skip only 6 races/rounds
(be aware that if you change team, you lose all of your resource points)
(Also make sure you start the race, if the race is not started you cannot choose "Retire from session", so just wait a few seconds until the red lights at the start go out and then you can press pause and retire from the session)
