How to enable nouveau / Wayland on ISO KDE / GNOME?

Trying to estimate current dev daily ISOs KDE / GNOME or just test some software in Wayland environment and all I get for Nvidia / Wayland is software rendering like llvmpipe. Is it possible at all to enable nouveau / Wayland from ISO? I am sure I run proprietary NVidia fine on my installation, but cannot even activate nouveau in ISO… Why nouveau is unavailable in ISO?

Nouveau is available in the ISO’s when you boot with free drivers. Simply in some cases is worse than the proprietary ones, and wayland is not set for live environment anyway, unless you create your own ISO with your own profiles.
