Disable LoopRotatePass from command line with clang

I want to disable LoopRotatePass from the command line using the flag disable-lrp with clang .
I was following the same way the loop strength reduction pass(disable-lsr) has been disabled from TargetPassConfig.cpp but it’s not showing any error but the code is not blocking or disabling LoopRotatePass.

Anyone has any idea , how to implement disabling LoopRotatePass .
