ESP_RF_Test_tool upload error

[Panometric]

The lab is scheduled, but the test tool will not upload over serial.
I can only assume it's because it changes the baud rate for upload from what is selected 115200 to 921600 which is more than my FTDI cable can support.

Is there a way to set the upload baud?
OR should I just load the BIN another way and not use this feature?
