It is achievable in Carrier mode but not until the second (level 2) Tatuus FA01 championship in Trofeo series where a proper race weekend is available (or around there in carrier). However it can be done in any game mode (I believe) I have unlocked it at Drive/Race weekend. Before the race set the proper amount of time for qualification to run your decent lap. The trophy pops when you start the race in pole position (beginning of the race not during or after qualification).
