Naming rule un Unity

Hello,
I'm using the last version of Resharper 2019.1 with Unity and I've an issue in my project, I have the warning "Name xxx doest not match rule "Unity Serialized field". I don't know where is this rule, the ones in Code Editing => C# => Naming Style does not seem to have an impact.

Could you tell me what option I should edit to fix my warnings ?

Thanks a lot,

Valentin
