Force CP Bypass on ADV7619 for all pixel clock rates?

This is a customer question:


I've got a question about the pixel port on the 7619. We'll need to use this part with HDMI sources with pixel clocks both above and below 170MHz. According to the datasheet and user guide, when the incoming pixel clock is >170MHz, the device bypasses the CP and outputs interleaved 24bit odd/even pixels with a clock that is half the incoming pixel clock. Is it possible to maintain this mode (force it) even when the pixel clock is less than 170MHz? This would save us from the pin-sharing that goes on between these two modes.
