I believe there is a way to do it by changing the Byte 18 value. Some other countries have front DRLs and always-on tailights (like rear drls). If I remember correctly, some guy had this on vwvortex a while back and he was using a Scandinavian code.
Look for a list of all the valid byte 18 values (there's a few threads with it)
Turn on byte 24 bit 7 to set drl as parking lights.
Also set byte 15 bit 6
