How do I disable Malwarebytes?

I am using the paid version of Malwarebytes. I want to also install McAfee "total protection" which is their top of the line product. Also purchased. I was advised to disable Malware bytes during McAfee installation. Another person said leaving Malwarebytes in place should be OK and that disabling it is impossible because disabling it is exactly what hackers TRY to do. How should I proceed? ( Note: I have no computer problems at this time. )
