Chia,
VSP is enable by default, if you would like to disable the VSP then you need to add the respective client in host properties and disable it.
While installing the client software if you choose custom then you will have 3 options out of which VSP is one of them, if you want you can deselect it and proceed with client installation.
If you proceed with standard install the VSP is installed automatically and it will enabled.
Recommended is to disable to VSP if you really don't need, our environment while installing the client we deselct the VSP so that it will not get installed.
