F1 25 game - problem with iconic drivers in coop career.

Hi,
I'm driving a co-op career in f1 25 with my friend. After finishing the first season we both changed our teams. Unfortunately, along with that, four iconic drivers appeared such as Ayrton Senna and Michael Schumacher, which ruined the vibe of the whole game. But we didn't find any option to disable these iconic drivers. Has anyone had the same or managed to disable this option?
