noUnusedLocals error while converting ts interface to ts with validation

While generating typescript validation file from typescript interfaces, there is the below function that get's generated but not used in the generated file itself. This triggeres a noUnusedLocals error because of the config in tsconfig file.

function m(additional: any) {
return { props: [], additional };
}

We don't want to manually edit this file everytime it gets generated when a new source interface is added.
Is there an option to exclude this function from being generated or any other way to circumvent this issue?
atm, I am working around this by using a sed command on the generated file. Thanks in advance.
