Is there a way to connect MODBUS 485 without using virtual com port?

I am trying to do serial 485 communication via ethernet using adam 4571.
For ASCII communication, you can change the setting of adam 4571 to connect without using virtual com port.
However, in the case of Modbus communication, communication connection is not possible without using Virtual Com port.
Of course, it is possible to connect the serial communication line directly to the PC, but it is not possible to install the serial communication line due to the distance from the PC and noise caused by the power line.
If you know how to connect Modbus without using Virtual Com port, please let me know.
