HDR is bugging my Achievements and making me crash my car

Is it possible to disable achievement pop-up in this game on PC. Whenever an achievement pops my TV goes into this elaborate process of blacking out to switch to SDR to show the achievement then blacking out to return to HDR. Each blackout is only 2s but by the time I see where I am after two flashing blackouts I’m usually way off the road and forced to rewind the race. I’d just as soon not see the achievement and review them later. Interestingly, this doesn’t happen on Xbox and my Win10 desktop is already in HDR so this has to be a Windows Live issue. Any tips would be welcome.

you can turn off achievement notifications in you xbox preferences and on you your Xbox App notification settings.

Have similar issues. My TV manages to show the achievement and go back, but then colors look washed out, and I have to tab out of the game and back in. Disabling achievements does not solve the problem, it’s just a workaround.
