How to avoid the interpolation, if the {} is there at the time of specifying code syntax

In the crewai task description I need to specify only plantUML syntax to denote the example in .yaml file, like this

#### 1.3.1 ステートノート
    ```plantuml
    @startuml
    state ProcessingState {
        note as N1 #LightGreen
        entry point
        end note
        entry: entry / setupResources()
        exit: exit / cleanupResources()
        N1 --> entry
        entry --> exit 
    }
    @enduml
    ```

since it contain the {}, its consider it as a interpolation, but i don’t want to interpolate this. This is actually a syntax.

how to resolve this. Kindly help me on this, please.
