Is there a way to prevent network access inside the VNC session?

[Da-Buche]

Hi,

For safety reasons, I would like to run Rocky-Unix without internet access.
I am fairly new to docker, I've seen there are some network options but during my trials when I removed netwrok access, it also prevented the VNC connection to succeed...

Is there a way to setup the container so VNC connection works but Unix has no other network accesses?

Thanks,
Aurel
