I don't know anyone that has it, but from what I understand, it involves absence seizures, right? 'Non-convulsive' means you don't stiffen up and start jerking rhythmically, and generalized means you lose consciousness.
Firstly, like any seizure disorder, the right medication will be important.
Since you don't have convulsions, the risk of injury is much lower, but even so, if you've been having seizures lately, be careful about any activity where suddenly freezing could pose a risk of injury. Don't drive any vehicle, including a bicycle, until your seizures are under control.
