Yes and no.
Yes you can use the rear trapdoor that has a VGA out opening.
No because the trapdoor is just a pass-through. It is not meant for the VGA connector to be screwed and mounted onto.
My interpretation is that it does not have means to properly mount the VGA connector, it may be just an opening and you can pass your VGA flat cable through it, but not secure it, it would be loose all the time

I hope I'm wrong.
