There are no specific means of configuring the IronKey EMS On-Prem to point to a Microsoft SQL Server named instance.
However, there is a workaround that involves configuring Microsoft SQL Server to listen on a different port:

Steps:
Install MS SQL Server for a second time to create a named instance. You will be prompted for an instance name - in this example, it was named ‘TEST’. Substitute your database name for ‘TEST’ in the steps below.
Restore the On-Prem database and create an admin user on this instance, as per instructions in the IronKey EMS On-Prem Setup Guide.
After installation, open SQL Server Configuration Manager.
Expand Network Configuration and select Protocols for ‘TEST’.
On the right-hand side enable TCP/IP and Named Pipes as usual. Then open TCP/IP.
In the IP Addresses tab make the following changes:
IP10:
IP Addresses to 127.0.0.1
TCP Dynamic Ports <blank> - note NOT 0
TCP Port <port> -choose a port that you want to use
IP2:
IP Addresses to IP of this machine on the domain
TCP Dynamic Ports <blank>
TCP Port <port>
IPAll
TCP Dynamic Ports <blank>
TCP Port <port>
Go to SQL Server Services and restart the service for ‘TEST’.
Now in the OnPrem CLI setup, use <port> in the application database configure step in place of the normal 1433.
e.g. - application database configure 10.99.50.94 <port> admin password mssql ironkey_es
Run command service start appserver.
You should now be pointed to the Microsoft SQL Server named instance.
