How do I select which hard memory controller to use if my FPGA has two controllers?

I am using an Arria V GX which is suppose to have 2 hard memory controllers. How do I select which one to activate as the UNIPHY memory controller seems to only work with bank 7 but my memory device ...

I have found a simple workaround:

By reserving one of the pins allocated for the HMC on bank 7 (e.g. the RZQ pin G6) the alternative HMC on bank 4 is automatically chosen during fitting.

Thank you for your responses.
