Leave them unconnected.

Do not connect them to VDD or VSS.

If you have room / cost add a pull up or pull down res. You don't have to
fit them in the final unit, but if you suddenly need a switch input - it's
there waiting for you.

If you choose to leave the lines totally unconnected, set them as outputs
in your software.

By doing this, you give yourself room for manouver (...spelling?) to catch
any last minute fixes.

Just my ten cents.
