BLE ER key and IR key

I see that those keys are hardcoded in the code.

As I understand they are responsible to LTK and CSRK.

Should I change ERK and IRK between devices , so they are not the same?

Asking for security reasons.

Is there a way to randomize them? I believe it is needed. (unless the BLE stack does it?)

Can I read them after I write?
