How to disable caching

I am using Bitnami to implement neos, I would like to know how I can disable the caching, is there any option in backend to do so?

Before disabling caches be sure to understand the implications and rethink why you want to take that action. It is often just fighting symptoms of a problem somewhere else, worsening the overall situation.

Anyways, to disable specific caches (there are many!), configure the affected environment (development?) to use the NullBackend for that caches.
To find out which caches are currently configured, execute ./flow configuration:show --type Caches
