How to change MAC in bluetooth HM-05?

Question

Arduino

Hello everyone, I recently purchased two BLE modules from Chinese friends, I couldn’t figure out which model specifically, I think it’s HM-05, the firmware is “+VERSION=Firmware V4.2.0,Bluetooth V4.0 LE”.

But bad luck, they have the same MAC address, which excludes their connection to the same master.
Can you please tell me how to change the MAC on one of the modules? Failed to google (((

Perhaps this is an analogue of the HM-10 module. Anyway, google the AT commands for it. For example, the HM-05 has "AT+BIND", "AT+NAME" and "AT+PIN" commands.
bluetooth.write("AT+BIND=xxxx,xx,xxxxxx")
