Another crazy idea for the author of qDslrDashboard.

You can send motion control commands to DDServer and then to a network device with a specified IP address via TCP- or UDP-based protocol (REST, MODBUS TCP and so on). For example, it can be an Arduino or Raspberry connected to the RJ-45 connector on the MR-3040.
As alternative - USB-connection between MR-3040 and Arduino (with USB-splitter) and serial-based protocol.
There are many possibilities for realizing original equipment for controlling the camera over the network.
If the program still supports follow focus, self-isolation will not be so bad.
