@JesseDuBord, as has already been mentioned by @memeplex, you can use dconf editor GUI to access all the features of Ubuntu Dock. They are located here: org.gnome.shell.extensions.dash-to-dock
The parameter you need to activate “true autohide option” is intellihide
.
To quickly enable it, you can use the following command:
gsettings set org.gnome.shell.extensions.dash-to-dock intellihide false
After that, turning on autohide option in System Settings will activate “true autohide” instead of the default intellihide.
To get things back just obviously run
gsettings set org.gnome.shell.extensions.dash-to-dock intellihide true
Have a nice day
