SIerra Modem LTE only AT Command

[mezmerizz0454]

OK i probably over looked this, I did search the forums for Sierra modem 4G-LTE only AT commands
i looked at BillA's posts and Jim's posts maybe i just over looked it, but I'm after the AT command for EM7565 and EM7511 to put them in 4g-LTE only mode

found the 4G-LTE only command for Quectel modems
AT+QCFG="nwscanmode",3,1

but need the one for Sierra modems please,.

Well i may have found the string i needed but would like confirmation so i don't do something crazy and brick my modem for Sierra modems it seems to be this

AT!SELRAT=06

would this be correct for LTE only bands?

Don't have those modems but have several other Sierra models (7455/7354). Should be the correct command, worst that could happen is you get an error back when entered.
