ONLY IF framebuffer support is selected (i.e. X11 = N), correct?
First, you're confusing the mouse driver with the cursor. The
mouse driver can be turned off in the config file, which will
then automatically result in no cursor being displayed. With
X11, the mouse and cursor are normally present.

Actually, that's incorrect. See drivers/scr_x11.c::X11_open(),
an empty (invisible) X11 cursor is created with XDefineCursor.
X11 allows different cursors in every window. Microwindows
always draws its own cursor, and instructs X11 never to.

No, that won't work.
To hide the cursor, add a GdHideCursor() as the last item in
nanox/srvmain.c::GsInitialize(). You might take a quick
look through this function to see how the cursor is initialized
in the first place.
