Both Debian and Ubuntu come with nonfree firmware blobs by default. Nonfree drivers such as the Nvidia proprietary driver can be installed graphically in Ubuntu if you open the drivers app.
Debian instructions are here and involves adding the non-free contrib
repos to your /etc/apt/sources.list
and then installing the nvidia-driver
package
Not even a single day practically.
