Just turn the NAV1 frequency to another frequency, and that would have

The marker beacon is an independent radio reciever that is not connected
to the nav radio whatsoever. It may or may not be integrated with the
audio panel, but there usually is a mute or speaker switch associated
with it. Changing the nav radio should have no effect on the marker
beacon reciever, since the same marker beacon reciever frequency is used
across the entire country (and world, if I remember right)
