What can i do to completely disable per pixel lighting?

Hi here,

i have 1 directional light in my scene. When i add a point light (set to “not important”) it gets rendered as pixel light - and so the drawcalls increase dramatically.
(quality setttings set to pixel light count: 0, all objects have vertex-lit shaders, any other added ligths are rendered as vertex-lights).

What can i do to completely disable per pixel lighting?
Thanks!

Set the rendering path to vertex lit.
