Peacock Network not free on all boxes?

I can get Peacock without any charges to view programs on one box but the main DVR box doesn't have the same access.  Some programs have a charge and don't have full access on the DRV box.  

Sometimes I get a message that I need to upgrade my box but worried that like in my past experience, I will lost other programs/channels and probably pay more $$.

Thank you in advance.
