Use it like any other built-in ESLint rules.

import eslint from '@eslint/js';
import tseslint from 'typescript-eslint';

export default tseslint.config(
  eslint.configs.recommended,
  tseslint.configs.recommended,

  {
    rules: {
      "@typescript-eslint/restrict-plus-operands": "error"
    }
  }
);
