you can grant execute privilege to the user(s)GRANT EXECUTE ON FUNCTION function_name() TO some_user;

That is not possible. Postgres doesn't store functions in the compiled
form, it stores them in the source form. Each process that executes a
function has to compile it first. If you are looking for something like
the Oracle "wrap", it might exist as an extension, I don't know. Please
be aware that even Oracle "wrap" is not very secure. There is a public
SQL*Developer extension which unwraps the wrapped source code.

Write it in something else than sql or plpgsql, and use external file.
But, if your function source is security vulnerability, then don't write
it that way.
Best regards,
