Do we need to configure Interrupt rate limiting on the processor per
application basis? If so, can I configure it on only selective

If a device supports it properly, it can be always be enabled. If the
amount of traffic is low, the device won't delay the interrupts (low
latency/bandwidth). Only if the interrupt rate is going up, and there
is still FIFO space available, the interrupt rate will be limited, which
trades off higher latency for higher bandwidth.
Consult the documentation of any devices capable of interrupt rate
limiting for exact details of this option.

No. But, It can be done by careful design of your system by you.
