I'm not worried about CELs, but I am concerned about car going into limp mode with this kind of code...
FYI here are a few websites that provide reference on this topic... unfortunately, nothing on the 370z yet

The general takeaway from all these forums seems to be that you can delete the system but have to find some way to then vent the gas tank, either through adding a valve to one of the delete lines and/or adding a vented gas fill cap... plus you need to disable an "EVAP" related codes in the ECU... does UPREV allow us to disable codes outright or only to reset them?
Plan B is to relocate the evap system to the cabin trunk area... I think so long as the system is sealed there is no issue with volatile gases being emitted to the cabin
