Hi @MDuBose
OOS is not an essential component of SharePoint.
When used with SharePoint Server 2016, Office Online Server provides Word Online, Excel Online, PowerPoint Online, and OneNote Online. Users can view and, in some cases, edit Office documents in SharePoint libraries by using a supported web browser on computers and on many mobile devices, such as Windows Phones, iPhones, iPads, and Windows tablets.
If you do not use OOS, the office file in SharePoint will be opened from the client, which will not affect your use.
You can refer to the following similar situations to refer to how to disconnect OOS and SharePoint:
