Permanently Lock Andersen 400 French Door

I'm building and we've decided to do our deck after our builder is gone and we have COO. That has left us with an exterior door that needs to be closed. I'm trying to avoid installing one of those segments of railing that gets bolted up. I plan to build the deck within the next two years and just paid a lot of money for these doors. I don't really want to drill holes in them?

My inspector says that if the door is permanently closed it will pass inspection. Any suggestions on how to make that happen for an Andersen 400 French Door? Do I just lock it then install a blanking plate instead of handle and lock on the inside?
