https://docs.python.org/3/library/tkinter.ttk.html#tkinter.ttk.Notebook 
lists add, forget, hide, identify, index, insert, select, tab, tabs and
enable_traversal, but no grid, possibly others.  yet:-

 >>> import tkinter.ttk
 >>> help(tkinter.ttk.Notebook.grid)
Help on function grid_configure in module tkinter:

grid_configure(self, cnf={}, **kw)
     Position a widget in the parent widget in a grid. Use as options:
     column=number - use cell identified with given column (starting with 0)
     columnspan=number - this widget will span several columns
     in=master - use master to contain this widget
     in_=master - see 'in' option description
     ipadx=amount - add internal padding in x direction
     ipady=amount - add internal padding in y direction
     padx=amount - add padding in x direction
     pady=amount - add padding in y direction
     row=number - use cell identified with given row (starting with 0)
     rowspan=number - this widget will span several rows
     sticky=NSEW - if cell is larger on which sides will this
                   widget stick to the cell boundary
