Lock Bootloader

[Xern]

Does anyone know if I can get the factory image for the Zenfone 5 ZE620KL? I unlocked the bootloader but didn't do anything but now I want to lock it again to get back play protect certification. Or does upgrading to Android 10 beta and then downgrading to Android 9 also lock the bootloader?
