EC25: Recognition of a submodel

Hi,
I’m looking for At-Commad to know the submodel of cellular module EC25

For Model I use:
AT+CGMM
EC25
OK

For Firmware I Use:
AT+CGMR
EC25EUXGAR08A08M1G
OK

At the moment I use EC25-EUX but in the future I need to I recognize a different module like EC25-AUX

Is there a AT-Command like this?
AT+XXXX
EUX
OK

Hello, you can use ATI to inquire.
Best wishes

If I use ATI command I have the same problem:

ATI

Preformatted text`Quectel
EC25
Revision: EC25EUXGAR08A08M1G

OK

As you see the submodel information is embedded in the string revision. I’m looking for a easy method like a AT command that responses with submodel string only.
