Can I lock EDID on a WATCHPAX server?

Is there a way to lock the EDID on the graphics card of a WATCHPAX?

EDID emulation is supported by WATCHMAX, WATCHPAX 40 and WATCHPAX 60. For WATCHPAX 2, 4 and 20 you will need an external hardware based EDID manager.

An EDID manager will make sure that disconnecting the cable doesn't trigger a reconfiguration of the displays but instead keeps it/them alive and the image comes back when the signal is resumed.
