Loader in parent route runs again if only a new child route is rendered

I would think that my loader only runs once in the parent route if a new child route is rendered, for example: loader in

dashboard.tsx

dashboard.tsx

only runs once if user navigates from

dashboard.users.tsx

dashboard.users.tsx

dashboard.roles.tsx

dashboard.roles.tsx

? But it doesn't. How can i possibly achieve this with file based routing?
