In AR project,how to still see the camera feed after turning off the "Enable Automatic Camera Tracking" option?

I’m working on an AR project in Unreal Engine, and I don’t want the virtual camera to sync with the phone’s position. I intend to control the virtual camera’s position through other logic. Therefore, I have disabled the ‘Enable Automatic Camera Tracking’ option. However, this causes the phone to no longer display the camera feed. Thus, I’m forced to enable this option again and uncheck ‘Lock to HMD’ in the virtual camera settings. While this solves my immediate issue, I believe keeping ‘Enable Automatic Camera Tracking’ enabled causes the phone to constantly compute its position, leading to unnecessary battery drain and heat generation. Does anyone know how to disable this option while still allowing the AR project to display the phone’s camera feed?
