Firmware Request: EC25-J need latest standard firmware to enable UAC

Hello,
I am using the EC25-J module, but I am unable to enable USB Audio (UAC).
Currently, commands like AT+QCFG=“usbcfg” return ERROR.
My current firmware version is:
EC25JFAR06A04M4G_DCM
It seems this DCM-variant firmware has locked these features. Could you please provide the latest Standard Variant firmware for EC25-J and the flash tool?

Module: EC25-J
Goal: Enable USB Audio (UAC)
Required: Latest firmware (Standard version), QFlash tool, and USB drivers.

Thank you in advance.

In addition to my previous request, I would also like to obtain the latest firmware for the following version as well:

EC25JFAR02A06M4G
