Is it possible to use share_xaxis for some specific subplots?

Hi

I use make_subplot for 3 rows and 1 columns, the first 2 rows are data plot and the last row is image. Iā€™s like to use same x_axis for the first 2 data plot, how to do it by excluding the last row? Thanks

fig = make_subplots(rows=3, cols=1, 
                vertical_spacing=0.05, 
                specs=[[{"secondary_y": False}],[{"secondary_y": True}],[{"secondary_y": False,"type": "image"}]],  #
                subplot_titles=(plot_title_1stsubplot,plot_title_2ndsubplot
                               ),
                row_heights=[0.7,0.15,0.15],
                shared_xaxes=False,
               )
