No sure if there is another module causing this.

 A basic ttk:notebook does not appear to bind to mouse wheel events in
any way:
    $ rlwrap wish
   % ttk::notebook .n
   .n
   % winfo class .n
   TNotebook
   % bind TNotebook
   <Destroy> <Control-Key-ISO_Left_Tab> <Control-Shift-Key-Tab>
   <Control-Key-Tab> <Key-Left> <Key-Right> <Button-1>
 Therefore this behavior appears to be arising from some other module
you are using.

This is ironic; I actually wanted this behavior for bwidgets notebooks, and to make it work on linux one binds to Button-4 and Button-5 to use the mousewheel. Perhaps something in your code is doing this too.
I posted an example of this in https://wiki.tcl-lang.org/page/notebook (last post at bottom) which mostly was to demonstrate a bwidget notebook with close buttons on each tab, but also included the mousewheel over the tabs for scrolling them as well.
