In summary I need to update unixODBC on the Elastic Beanstalk PHP instances, preferably using yum as it's quite easy to manage via .ebextensions.
- AWS Linux: 64bit Amazon Linux 2017.03 v2.4.2 running PHP 7.0
- Needed unixODBC: 2.3.1
sudo yum info unixODBC

I found 2 related posts for this here on serverfault but they no longer work. One suggested I disable yum priorities, which I did, but that did not change.
