If that's a UI question, you can choose "healthy nonsmoker" in the mortality table drop-down, or uncheck "death" to remove it entirely and get a more-standard retirement calculator that assumes you're living at whatever age you calculate out to.

If you mean you want to decrease your odds of death, then "healthy nonsmoker" is also a good start, and there's a very deep rabbit-hole you can go into on longevity research, though no real option to uncheck "death" yet.
