How to add only Workstation, not Gateway?

I sometimes want to add another workstation, or use CLI gateway with XFCE workstation. But with the new system where both get added at the same time, this is inconvenient.

Any way around it?

Should be possible to select only one VM in VirtualBox GUI.

And/or VirtualBox command line import feature m, i.e. importing VirtualBox VMs using vboxmanage command line in terminal. See VirtualBox/XFCE / VirtualBox/CLI wiki page. Expand footnotes. Import command there. Same as VirtualBox vboxmanage command. VirtualBox feature.
