iMX.6 IPU Adv7611 external syncs

I have a system on the iMX6Q using the ADV7611 configured for BT.1120 YUV4228.  Everything is working fine, however, we are having an issue when it comes to passing compliance.  One of the suggestions was to switch to using external syncs (vsync,hsync,de).  I wanted to confirm that given the pinout from the ADV7611 seen below and what I'm reading in the iMX6 reference manual, specifically the IPU Sensor Interface Signal Mapping section, that it is not possible to switch to external/gated clock mode?  The subnotes 7/8 state that syncs must be embedded in the signal.  Essentially just want to confirm that I'm interpreting this correctly. 

 

Thank you
