CUDA installation on favorite driver on Windows 7

My question may be obsolete for the 2021 year developers but this is my problem. I want to install the NVIDIA CUDA version 6.5 on Windows 7. I downloaded it from [CUDA Toolkit 6.5].
When the installation starts there is no option to choose the installation driver. It installs the CUDA on the OS driver by default. My OS driver does not have enough space for it. Is there any option to customize it? (CUDA Toolkit 6.5 | NVIDIA Developer)

Did you try the “Silent Installation” options, mentioned in the “Windows Getting Started Guide”?

I worked on it. The problem now is the package installed near 6GB, 2GB in my custom path, and 4GB in OS path.
