No, not as far as I know.  You have probably seen this thread, which is
without success so far:

There are similar (or the same?) issues with the E3372:

I don't really know what is going on here.  Looks like "NDP to end" is
not the (only) problem.  The symptoms are similar to what we saw when I
messed up the setup sequence: The modem silently ignores our
SET_NTB_FORMAT reuquest and continues to operate in 32bit mode.  So I am
wondering if it might be a problem with our setup.  Maybe the modem
doesn't like being told to do 16bit mode while the buffers are > 2^16?

If you have the hardware and can reproduce the problem, then it might be
worth trying to move the initial buffer setup before the SET_NTB_FORMAT.
Maybe cdc_ncm_setup(dev) can be moved into cdc_ncm_init(dev)?  I don't
remember why I split it like that...  Might have been a good reason.
Or not.
