It will have some sort of thrust bearing between the static release mechanism and the rotating clutch . The clutch may be released hydraulically, or mechanically with pivots,levers, release forks etc.
If you are lucky the squeak may be from external hinges, return springs etc on the clutch pedal etc that might improve with some lubrication .
If the squeak comes from the clutch mechanisms within the bell housing itself it might only be cured with a replacement clutch. And its normally good good practice to take the opportunity to replace all 3 parts, whether they need it or not. Pressure plate, friction plate and thrust bearing . And possibly also the release hydraulics.
Or maybe the clutch will remain serviceable for a long time yet if you can tolerate the squeak. I would describe a worn clutch release bearing as a sort of continuous rumbling all the time you are pressing on the clutch pedal, rather than a brief squeak as you press or release it.
