Verizon Note 3 flash?

I just purchased a Certified pre-owned Verizon Galaxy Note 3 off amazon (SM-N900V android version 5.0 kernel version 3.4.0 KNOX version 2.3) and I have the free assurance wireless lifeline service with the free cheap phone and wanted to know if I can flash my note 3 to this service? (the note 3 came with a Verizon sim card that I have not put in the phone yet ) any help would be greatly appreciated
