Yes – You can erase the user mode interrupt handler routine. You can also implement some of the interrupt handling in the Kernel PlugIn and some of it in the user mode. The return value of KP_IntAtDpc() (which is called when the high-priority KP_IntIrql() routine returns TRUE) determines the number of times that the user mode interrupt handler routine will be executed (if at all).
