Test the iPhone 11 upper layer logic board to check if it's same as the previous iPhone can be turned on by a single logic board. After testing, yes, it can, just be baseband.
The iPhone 11 uses the fastest A13 chip,put iPhone 11 motherboard under a Trinocular Microscope, and then use hot air gun and BGA graver to remove the iPhone 11 CPU.
