The Necrons have multiple options they can take to stop the Tyranids or prevent their destruction by the Tyranids.

1. Wait until the entire Tyranid race enters the Milky Way Galaxy, then the Necrons can activate the Celestial Orrery.

2. Go back into hibernation and make sure tomb worlds have hardly any biomass Tyranids could want.

3. Szarekh unites the entire Necron race against the Tyranids, starting a massive galactic war, ending with a Necron victory.

4. The Necrons trick the Tyranids into the Eye of Terror, and the Warp if possible, then seal the warp and Eye using pylons.

5. The Necrons decide to awaken their whole race, form brief alliances with other order races, and all beat the Tyranids together.

6. The Necrons manipulate the Tyranid gene pool and place in genes such as the Pariah gene so that the Hive Mind's connection is endangered and a schism begins with the Tyranids.

7. The Necrons possibly find the Old Ones, denounce the C'tan and attempt to make amends with the Old Ones, so that the Old Ones can help the Necrons defeat the Tyranids. (Extremely rare scenario).
