xvidtune doesn't support this.

But it wouldn't be a great deal of work to modify it to do so. 
xvidtune consists of a single source file, with roughly 1300 lines of
code.

Essentially, you would need to open a separate X connection to the
display being tuned, and pass that display to the XF86VidMode
functions rather than passing the display used by the GUI.

No. By default, the X server only allows local clients to use the
VidMode extension, so you have to run xvidtune on the same host as the
X server. That option removes this restriction, allowing any client to
use the extension.
