Sure... you can buy a two lamp ballast. Will it work.... maybe.

Usually the electronic ballasts will work with one tube but the tube may not last as long.
A standard old style magnetic ballast may not operate with only one tube.

If it's instant start electronic you can usually simply cap one of the blue leads. Read the label on the ballast. If it lists 1-lamp, then it's OK. Many do.
