Quite possible.  This countermeasure was discussed more than ten years
ago.

It is possible to turn of the civilian signals -- or to leave then on
but _jam_ them within a selected area -- without interfering with US
military use of the satellites.  A modern military does not need the C/
A code to acquire lock on a satellite.  It can acquire the encrypted P
code directly."
