DJI would be breaking local laws if it allowed its products to changed so they don't comply to local laws as you appear to be asking for.
Not entirely correct, previous DJI models (I believe the Phantom 2 Vision) had a CE/FCC switch in the back, and users were responsible for setting it correctly.
Do you understand what impact such actions may have on others due to illegal transmissions?
Let's not be so dramatic... we're not talking about transmitting at high power on reserved frequencies. Increasing the power output from CE to FCC levels on a P3S is not dissimilar to - for example - putting bigger antennas on your WiFi router so it reaches the other side of your house. Yes, your signal will travel farther... but in the case of a drone, which is typically operated in open spaces, the "impact on others" is near zero.
