Disable UART wires on mIDAS-Link debugger when connecting to ADuCM355

Is it possible to disable the 2 UART wires on mIDAS-Link debugger, and only use SWCLK & SWDIO, when connecting to ADuCM355? What settings would get this done? And will mIDAS-Link lose any features by not using UART for debugging connection?

In my application, the only UART interface on ADuCM355 is used for external RS485, and I need to run real time debugging via mIDAS-Link.
