First of all: why do you want to disable polling? Does it cause any problems?
Second, are you sure, udisks is actually polling your drive?
You probably have a SATA AN capabable drive, which does not need polling and
instead sends (udev) uevents on media changes.
That's why you can't disable polling, as it actually doesn't poll :-)

Do you have a file evt_media_change in /sys/class/block/sr0 ?

Cheers,
Michael
