There isn't a way to do that exactly but you can manipulate the shading by going to Options > View > "Lighting options".

Try setting Lighting style = "Custom key + fill levels" and then you can tweak the light source intensity by sliders and also for more illumination you may want to turn on specular highlights with a low focus size which will make a broad highlight.
