I have had some doubts about Dell installs which had non-free blob dependencies which were "insert USB stick and hit enter" -when I am doing remote install via virtual media. Mainly this was for broadcom ethernets.
I found in the end, proceeding to install and then post-install patching was easier but tedious.
If you have access to USB slots, this is a non-problem. If it were possible to find and make and maintain "CD with a bit of the blobset glued in" I'd be happier frankly.
