how to hide mirrored line

Hi, I'm intend to hide the mirrored line that run through the mid fuselage. is there is anyway to do that? .

If I'm change the display to shaded, all the split line (windows, door and etc) will not be seen and that is not what i'm intend for.
FYI in mirror feature, I ticked on the 'merge solids' and 'Knit surface'.

UPDATED 2 :

I have uploaded cad model with split feature
