Well, the modem is something like a headless Android phone. At least, it uses the Android bootloader (Fastboot) and an Android-like downstream kernel. But it does not run the Android userspace, so it should be free of Google services and the like. There is the unofficial firmware from Biktorgj which has fewer proprietary components, so you can know better what it does. But it does not replace the Fastboot bootloader, the Trustzone kernel nor the DSP firmware, only the main OS running on the modem's ARM CPU, and the kernel it ships is based on Quectel's downstream kernel sources (based on the ancient Linux 3.18.140 whose upstream support on kernel.org ended in 2019).
