Asus 4G-AC68U support

I see the AC68U on the list of compatible devices but not the 4G version, with LTE modem included.

I want to build an OOB device where I could ssh into via LTE. Could this be done using this device or are there better recommendations ? Reason I'm doing this is that dedicated hardware companies, such as OpenGear are all out of stock so I need a stop-gap solution in the meantime
