Restoring USB access after disabling it through AT comman

IoT Modules LPWA Module
1

Hi every body,
Due to cyber security reasons I tested to disable the USB port using AT command AT+QCFGEXT=“disusb” (with commad 1 , I think). The device works as expected and the USB port disappeared.

My question is if it is possible to re-enable the USB port back to its original operation mode so that a new/updated application firmware may be loaded?

I managed to get the device into “emergency download mode” (using the USB boot pin) and reload modem firmwware but that did not restore the normal USB port operation.

Thanks
