Theoretically it is possible, although at most one would expect a slight increase in latency, not freezing or stuttering unless it was getting positive hits and not allowing the traffic through at all.
Would be easy enough to test. If you turn off the real time scanning launch MSFS fly around a little do the stutters and freezing go away? Do they come back when you turn it back on? I would strongly recommend if you do test this in this manner, that you close everything, only launch MSFS do the test and the immediately turn scanning back on.
