Old patch to New patch steam update Question

[PotNoodles]

I was just wondering if there is anyway I can get steam to not update to the new patch if it stays similar to this alpha release? I thoroughly tested the game last night flighing through cloud..etc and I get about 5-10 FPS more with the old patch and no double FPS for me in this new patch. If steam did happen to update it and I didn't like it could I then roll it back to the version before? My specs below.

Gainward Geforce 680GTX

S!

Disable autoupdate in Steam on CoD and it will not apply patches automatically.
