Unfortunately this is not possible. There are a number of functions within NNMi that are hardcoded to certain user levels and they can't be overridden, even if you find the menu action in the UI configuration and change the settings there.
In the nms-topology and nms-ui properties files in the <NnmDataDir>/shared/nnm/conf/props/ directory you will find some settings that allow you to configure a level 2 user to be able to delete objects and work with nodegroup maps, but I don't believe these extend to the Custom Attributes function.
I would suggest you open an ER to request this capability if its important to you.
All the best
