The hidden session not to disturb the user

[black1]

As it is possible it will be connected to the remote personal computer, without disturbing the user, for installation of software, or control.
Somehow by means of session?
As slightly I edited a chat with the user, I added there the teams similar to runas

Can eat sense to add? (remote performance of teams)

Also console access, not interactive is sometimes necessary,
to execute something by udaleenny car conveniently having gathered in command lines. similar to ssh, cmd remote.

not possible; vnc can only clone sessions

It is impossible so not probably.
and if to realize the principle beyond a desktop of the user.
that is to display the program in not visible part of the monitor (1280х1024) for the user. it is so possible?

At its core, VNC provides remote access to the computer's screens. This means what the remote viewer sees and what the person in front of the computer sees are the same.

There are innumerable solutions available for remotely manipulating a computer without affecting the local session, but VNC is not one of them.
