Desktop icon for mounted NAS volume changes location and it annoys me

Question relates to the desktop icon for a mounted networked drive. MacOS 10.14.6 - Seagate NAS SMB - Computer stays on and is set to never sleep. Airport Extreme. I mount the drive/volume and I get an icon. I put the icon in a specific location and then at some point it moves to first available location on desktop. How can I make it stay where I put it? It's not a huge thing but it is annoying. Every other icon on my desktop stays where I put it (Time Capsule drives, Time Machine USB drive, internal drive, files, folders, etc.) My hunch is that the connection to the drive times out and then automatically reconnects, during this process the icon goes away (connection to drive ends) and then comes back and goes to first open location (connection to drive is re-established). Any ideas on how to keep my NAS drive/volume icon where I put it?
