Steps to reproduce:

1. Install zabbix-proxy-sqlite3 using https://git.zabbix.com/projects/ZT/repos/kubernetes-helm
2. according to https://www.zabbix.com/documentation/current/en/manual/config/items/itemtypes/odbc_checks try following:

odbcinst -j
ls -al /usr/lib/ | grep libmy

I haven't found a way how to enable some ODBC driver in Docker image or how to customize following via helm values:

/etc/odbcinst.ini
/etc/odbc.ini

Result:
Unable to use (especially MySQL) ODBC checks https://www.zabbix.com/documentation/current/en/manual/config/items/itemtypes/odbc_checks using ZBX proxy in K8S installed by https://git.zabbix.com/projects/ZT/repos/kubernetes-helm

Expected:
ODBC drivers installable+configurable via Docker env. variables / helm values.

Maybe there is another way, how to do it, but I don't see it.
