Validation of path parameters

[AliKHODR]

I am sorry to ask my question here but i can't find a way to validate path parametes in api-platform.
Ex: for the following route: uriTemplate: '/companies/{ref}/employees', i wan't to make sure that {ref} is a valid string before hitting my database and returning http code 404.
The only solution i found on stackoverflow is this: https://stackoverflow.com/questions/73417064/api-platform-how-to-validate-parameter.
is there a way to do this in api-platform?

Thanks
