If Fios is not in your area, you'll have to wait for them to decide to expand. Depending on where you live, this may not happen as they may decide to deploy 5G Home Internet instead of Fios. I've seen many requests like yours over the years, and they all end the same way - wait for Verizon.
If you think the lack of Fios is due to an error in their database, contact their social media support team and ask them to open a FAST ticket. This causes their engineering team to review their information and see if they've missed an address that can get Fios. To reach out to this team, tweet @verizonsupport or DM them on their Facebook page. However, given your description, I don't think they will have the answer you want.
The only other approach I can think of is to raise many billions of dollars to get enough shares that get you a seat on the board, then you can have a say in how they allocate their resources. And make sure that the result has a positive impact on the stock price; as that what board members are supposed to do. But that's more of an Elon Musk play than what an average person would do. 🙂
