It seems you're referring to .rc file for evs manager service (/packages/services/Car/evs/manager/android.automotive.evs.manager@1.0.rc).

The explanation for this and all other possible options can be found in the official Android Init Language documentation:

priority <priority>

Scheduling priority of the service process. This value has to be in range -20 to 19. Default priority is 0. Priority is set via setpriority().

Therefore, priority -20 means the service will be scheduled with the lowest possible priority.
