In my render TOP I see the shadow of all geometries, even if I want to render only geo1 but not geo2 (or opposite). The only way to remove the shadow of not-wanted geometry is its render flag via script. But if I have many geometries and want to render some of them depending of circumstances calling the render flag any time is not very performance wise, isn’t it? Is something wrong here? I guess it’s not normal to see the shadow of geometry if I don’t have it in geometry parameter of render TOP.

Check your light’s parameter for shadow casters:
Ah ok, this is the night of obvious things 
I just found it the other day when I was having a similar issue - sometimes these things hide right in front of us.
