No you cant 
When you use fully dynamic setup, you should do 2 things first: set “force no precomputed lighting” to true and put “AllowStaticLighting=0” into console variables. Those settings prevent you from getting any reflections from either the movable skylight or reflection capture actors. At least in 4.4.3. I remember having builds before December QA where it worked when you disabled reflection environment lightmap mixing but that doesnt work anymore. You have the new option diffuse from capture, but sadly it then applies the diffuse GI from the skylight twice
