Some are supported dynamically when the correct gvfs integration is installed, e.g. gvfs-smb. This has eventually been deprecated by gio. The gio command can also be used to control gvfs from the command line.

There are environment variables which can dynamically deactivate certain features and that leads to unclear error messages, e.g.

GIO_USE_VFS=help gio list network://
gvfs - 10
local - 0

GIO_USE_VFS=local gio list network://
gio: network://: Operation not supported

GIO_USE_VFS=gvfs gio list network://
