I just went through this yesterday! I did a big upgrade on my wife’s computer, fresh install of Windows on a 2TB NVMe drive replacing the aging 120GB SSD that somehow didn’t completely fill up, etc. Etc. really loved pointing epic at the installs on the secondary drive and it just ignoring them and instead spending 3 hours downloading Fortnite after we just spent 1 hour applying the last update yesterday (and another hour on a different update the day before too!) on the drive that’s RIGHT THERE IN THE COMPUTER!
