It is possible but somewhat uncommon in books. When you say frequency, we often imply periodic frequency, where the period of time remains constant (and so does frequency).

Non-periodic frequency is also possible if you count, say, N events in time T. So N can vary in this. Then the frequency is f = N/T. In other words: FPS = Frames / Time (1s) = Frequency.
Note that this print can be deceptive. You can also calculate events for a shorter time T while still using Hz. You will then see the instantaneous refresh rate of the image (which can fluctuate very quickly), but not really the frames per Secondly. If you want to know exactly how these fluctuations are going, you can also look at the tire times.

Especially in electrical engineering, we use Hertz at (fundamental) frequencies that do not change. Unwanted fluctuations of this frequency are then expressed by models/measurements, such as phase noise (analog/RF) or jitter (digital). Funny anecdote: Phase noise is often also given in turn for each frequency – after all, you can also measure how much/how fast the time period changes over a given period of time.

So all this is allowed.. Neither of the two descriptions I have read here I will not find false or true. Personally I would prefer to see the name FPS instead of Hz, just as I read my DDR4 speed in MT/s instead of MHz, but I get what you mean..
