I’ve seen videos that show having two touch enabled cards next to each other prevents anyone from scanning, since their signals cause interference with one another.
I came across the video when looking up those RFID blocking cards you can add to a non shielded wallet and they work the same way
I have a beefed up Intel NUC running Proxmox (and my self hosted services within those VMs) and a stand alone NAS that I mount on the necessary VMs via fstab.
I really like this approach, as it decouples my storage and compute servers.
