Hi @EmanueleP ,
I think the original NXP component does not support the KEA parts (I might be wrong). Anyway, I'm using the McuOnEclipse FreeRTOS component which does not have such a dependency on the clock manager:

I'm not developing anything on the KEA family (I had used the KE one), but if you want to consider that alternative FreeRTOS component, I could look into it.
I hope this helps,
Erich
