Aod on / off for different kind of sport activities

I want to turn on or off AOD for specific sport activities. For example, on for running but off for hiking. On the Epix Pro, I simply created a power mode to change that. This is, however, not possible with the F8. When I go to focus mode and set AOD to „ don't change“ and add a power mode to my activity, the display still turned off (in smartwatch mode, I also don't use AOD ) despite creating a custom power mode. Has anyone figured this out?
