TUSB546A-DCI: USB 2.0 & DisplayPort over USB type C

Part Number: TUSB546A-DCI

Hello!
I have a question about DisplayPort over USB type C alternate mode.
Now we are working at the project of device that act as a video signal source and should implement only USB 2.0 link and 4-lane DisplayPort (without!!! USB 3.0) alternate mode over usb type C. 
I have seen UFP_D Type-C Receptacle Pin Assignments for Normal Plug Orientation & Flipped Plug Orientation (VESA DisplayPort Alternate Mode on USB Type-C Connector Standard) and I found that it is done so that there is no need for use extra mux for flipping DP-signals. In out another project we use TUSB546 for muxing HDMI & USB 3.0 signals, but here we don't have USB 3.0 link.
My question is: could i route my 4 DP-pairs directly from DP-driver IC to type C connector without using any SS-MUX. I have brifly looked throught specifications and coudn't find any forbiddance. But i'm still worry is it correct to do it in such a way?
