Is active record support possible for IBM DB2 in CodeIgniter?

I'm currently working on a project using CodeIgniter with an IBM DB2 database. Since there isn't an inbuilt DB2 Driver package available for CodeIgniter, I've created my own custom class. However, this means I can't utilize the active record functionality.

Is there a solution or method to work with IBM DB2 in CodeIgniter while still having support for active record functionality?

I would greatly appreciate any assistance. Thank you in advance.
