LVDS Signal DC offset and AC Swing

Quite clearly the 0.4/0.5 Vocm spec is quoted from c10gx datasheet. You have been previously asking about transceiver ability to connect with LVDS IO standard. As far as I see, MIPI D isn't using LVDS levels.

My brief reading of the transceiver spec tells that it supports two VCCT levels, resulting in the said Vocm values, but I didn't analyse it in detail. I however doubt that varying VCCT beyond the specified levels is a good idea. If you need to adjust Vocm for a DC coupled link, you better think about resistor networks. In a first place I would check if the involved peer can work with the signal level exposed by the transceiver.
