Firmware 3.12.1 and REVO6

I have a REVO6 hotend and just upgraded to 3.12.1 firmware. Now this new function (Temp Model Calibration) will not allow my printer to run because it can't calibrate. I keep getting a Thermal Anomaly error. I found info saying that TM Cal has to be turned off with the REVO6 and found the commands to do so, however I can't find a way to send these firmware updates. I am not running Octoprint or anything like that. I downloaded Cura cause I know it has an area to push firmware logic, however Cura is not recognizing the USB cable and I keep getting the message in the attached picture. What are my options? TIA.

You can use Pronterface that comes with the Prusa driver install to send commands to the printer.

ProtonInterface is not supported on later versions of Mac OS and M1 chip
