I have another idea besides killing synapse creatures, what if the non-webway and warp races of the galaxy scarred and burned most of their worlds to get rid of biomass and basically hide from the Tyranids (unfortunately this would mean the Imperium would have to shut off the Astronomicon) But doing this has the possibility of forcing the Tyranids to look on to another galaxy and basically think there's nothing in the Milky Way. The forces of Chaos, the Dark Eldar and the Craftworld Eldar could do this easily however I'm not sure if the Imperium could pull it off at all.

In conclusion probably the only way to get the Tyranids to leave the galaxy is for the Imperium to fall and the Astronomicon to be shut off. Which would mean the Emperor must die first.

"So yeah, Nids are the strongest faction in 40K because nothing actually within 40K can beat them." Don't forget about the Old Ones (which are possibly responsible for the Tyranids themsleves) and the War in Heaven Era Necrons could have equally challenged the Tyranids.
