Spoofing of IMEI number on a librem phone

I have a question regarding librem phone. Since its running Linux and since I would imagine I have root access, I was wondering if its possible to spoof IMEI number as it may be banned in Australia, a lot of phones including OnePlus 7 was banned due to VoLTE Australian support requirements.

Since wifi mac address spoofing is possible as afaik the operating system reports the mac address of the wifi adapter to the modem, wouldn’t it be the same with IMEI spoofing?
