Answer ⇒ Yes. Static friction can do the non-zero work on the object.
Explanation ⇒
Static friction can do the non-zero work on the object. Non-zero work means the Positive work.
Example for that is given below ↓
Assuming that the one object (say A) is kept over other and lower object(say B) starts to move with constant acceleration in such a way that object A will not be slides over the object B.
Now, when the Object B moves it will apply the static frictional force on the Object A and thus the Object A will starts moving in the same direction of the static directional force. Thus, work done by the static friction will be positive.
Positive work is the non-zero work.
Hence non-zero work is done.
Hope it helps.

HEY!!

▶️Yes. Let us consider an elevator accelerating upward with a body placed in it.
▶️In this case, the normal reaction offered by the floor of the elevator on the body is greater than the weight of the body acting in the downward direction.
▶️If a person is observing this from the ground, then, for him, the normal reaction is doing a positive work, as the elevator is moving upward.
