Downgrading to High Sierra 10.13.4

I have an iMac and a MacBook Pro and I want to downgrade them to High Sierra 10.13.4 so I can install my Nvidia GPU.

Whatever I download from other websites can't be installed.

10.13.6 doesn't help me, I only need a link to download 10.13.4


Thank you

MacBook Pro
