How to disable 1 of GPUs for personal use during mining?

[Vanila]

  Hello everybody, i have a gpus mining rig on 4x Asus rog Gtx 1070  and 1 gtx 1080 Armor (MSI).
The thing is that couple hours of a day i need to use 1 of gpus to render some video, do some benchmark, play videogames ecc. Now im mining zcash with 0.3.4b miner for zec.
So the question is - how can i disable 1 gpu from mining for couple hours to use it by myself and then put it back to work?
(Maybe its a very stupid question but after googling it i found only some specific information about AMD cards only).
Thanks everyone who can help somehow! ^_^.

Very simple : the mining software have a specific option to design wich GPUs to use.
The only difficulty is the syntax : it an vary from one software to another : you have to learn the help command or to try some syntaxes.

The Cuda option work only with nVidia GPUs and don't work with all mining softwares.

I know that it is possible, but i never did it before and im not a programmer. Can somebody give me a good advice how to actually do it with using EWBF zcash cuda miner 0.3.4b?
I tried to look somewhere by myself but i cant figure out how actually do it. I apreciate every advice and help =D

hmm, you got an answer already. In you .bat file add  --cuda_devices 0   
(  Space-separated list of cuda devices. Without this option all devices are used.)
