setTurretOpticsMode and setTurretOpticsMode could perhaps be extended to work with pilot's turret path [-1], for Pilot Camera zoom.

For context, other ways to control pip screen, custom info panel, pilot camera, or turret include:
TransportNightVision keybind works for MBT reverse cam pip
setPilotCamera... commands
lockCameraTo command
Custom Info panel mode when on GunnerView on AH-99 Blackfoot works to cycle vision mode of pilot's pip screen
setTurretOpticsMode works to cycle zoom mode of pilot's pip screen

Such control would greatly improve the usefulness of pip and customInfo views of the pilotcamera. Base game control exists for vision mode, slew and stabilization can be scripted, only Pilot Camera zoom seems to be inaccessible for now.
