Depending on what kind of protection they have in place, that may kill the electronics. You may not care if it’s a separate cellular device, but will if it’s part of the head unit. Your best bet if you actually want to do this would be replacing the antenna with a properly matched dummy load. But that (or removing the antenna at all) is going to just leave you with exactly the problem you already have—it can’t make a connection, so it will continue retrying (and probably at its highest power setting) forever and drain your battery.

>But that (or removing the antenna at all) is going to just leave you with exactly the problem you already have—it can’t make a connection, so it will continue retrying (and probably at its highest power setting) forever and drain your battery. The majority of the power being drawn occurs because the system mistakenly believes the band is still usable and assumes that it probably just located somewhere with poor reception. This causes the system to ask the radio to bump up its radio power and when that doesn't work, wait x amount of time and then try again. However by stripping the cellular antenna, we make it impossible for the system from executing that behavior. Sure it'd periodically wake up and inevitably fail to initiate a scan but that consume vastly less power. (to the point that it'd likely be a non-issue)
