Default [Q] How do I disable update notifications?

I recently bought my M8 and I'm not sure if I want to unlock bootloader/root/S-OFF yet.

I've already downloaded the update and I can see the file in my download folder. I continue to get the notification asking me to install it. I don't want to install it yet, in case we don't get an exploit(?) for the update. But I also don't want to be asked constantly to install the update. How can I turn it off? Is it as simple as renaming the file?
