### Disable Plugins with Environment Variables
Plugins can be disabled without modifying and redeploying code.
`OTEL_NO_PATCH_MODULES` accepts a
comma separated list of module names to disabled specific plugins.
The names should match what you use to `require` the module into your application.
For example, `OTEL_NO_PATCH_MODULES=pg,https` will disable the postgres plugin and the https plugin. To disable **all** plugins, set the environment variable to `*`.
