No, you can not use any set-top box for cable TV because Cable TV operators provide a particular security system called CAS (Conditional Access System).
This CAS is used by Cable TV set-top box manufacturers. The conditional access system (CAS) and subscriber management systems (SMS) are two main pillars of delivering broadcast services in a secured and encrypted manner to authorized cable TV subscribers.
So if you are purchasing a set-top box from the market for your Cable TV line then it may not work because your Cable TV may have another CAS. So you should buy a set-top box only from your Cable TV operator Because it will be paired with their system.
