Nikon 5400 and 5700: change f-stop and shutter speed

Hello to everybody!

I've started studying and using libgphoto2 a few days ago and I'm finding
it very useful both to understand how to communicate with digital cameras and  
to do time-lapse photography with the Nikon 5400 and 5700 cameras.

I have a question about the limitations of those cameras. I've understood
that it is not possible to change the f-stop, shutter speed and exposure 
compensation remotely because it is not supported by the cameras: 
can anybody confirm this?

If so, I would really appreciate to have some information and maybe 
suggestions about which cameras do support remote change of f-stop and 
shutter speed.

Thanks in advance for your help!
