Clearly it does support it, since it works correctly. The message is a false 
alarm in the version (perhaps Ubuntu packages?) that you are using.

I would recommend:

1. ignoring it.

If Option 1 isn't practical (e.g. it fills your logs), there are two more 
options:

2.  Upgrade gdal to at least 3.5.1. This may require also upgrading cascading 
dependencies depending on your environment.

or 

3. Patch your packages to include the IGEOLO creation option in the list of 
those supported. That looks like:

https://github.com/OSGeo/gdal/blob/master/frmts/nitf/nitfdataset.cpp#L7132-L7135

(although if you're just patching that part in, the "Normally automatically 
set." part isn't true.)
