Is there a way to prevent Marshmallow from installing after download?

[MaguMLMM]

I have the Tab S2 64 Gb Wifi only. Last night Samsung pushed a download of Marshmallow to it. I have not installed it though, because I am not happy with it based on what I've experienced on my Note 4 and what I read here. Is there anyway to stop it from making me postpone the install every few hours? I have NO desire to install it until these bugs are resolved.

You should have turned automatic updates off before they pushed through the update otherwise you now have to keep delaying it since it downloaded but hasn't installed on your device.
