If so, the feature can just be turned off. However, if you are referring to retroactively removing previous awarded achievements for the removed tracks, then no. Because of the way the achievements feature works, once an achievement has been awarded, it cannot be rescinded. Similarly, achievements cannot be retroactively awarded.

By the way, only custom tracks can be removed. The default/built-in tracks cannot.
