I’ll send you the latest firmware via DM. Flash, and set the update rate to 5Hz with the $PQTMCFGFIXRATE command (on the module, that is). How exactly, you need to find out yourself since nobody here has gotten their hands on the actual module yet 
In Ardupilot 5Hz should already be the default setting, but double check: GPS_RATE_MS: 200
