CubeMx generates cmsis-v1 functions when using FATFS+FREERTOS cmsis-v2

I am using cubeMX 6.6.1.

When selected FREERTOS cmsis-v2 and FATFS, everytime cubeMX generates code it oveerrides syscall.c with FREERTOS cmsis-v1 prototype funcions.

int ff_cre_syncobj (	/* TRUE:Function succeeded, FALSE:Could not create due to any error */
	BYTE vol,			/* Corresponding logical drive being processed */
	_SYNC_t *sobj		/* Pointer to return the created sync object */
)
{
 int ret;
 
 osSemaphoreDef(SEM);
 //*sobj = osSemaphoreCreate(osSemaphore(SEM), 1);//cubeMX generates this
 *sobj = osSemaphoreNew(1, 1, osSemaphore(SEM));///cmsis-v2 equivalent
 ret = (*sobj != NULL);
 
 return ret;
}

int ff_req_grant (	/* TRUE:Got a grant to access the volume, FALSE:Could not get a grant */
	_SYNC_t sobj	/* Sync object to wait */
)
{
 int ret = 0;
 
 //if(osSemaphoreWait(sobj, _FS_TIMEOUT) == osOK)
 if(osSemaphoreAcquire(sobj, _FS_TIMEOUT) == osOK)
 {
 ret = 1;
 }
 
 return ret;
}

is there any way i could prevent cubeMX to override this two functions every time GENERATE CODE is clicked?

is this a cubeMX bug? or is it expected?
