{
  "rules": {
    "@typescript-eslint/no-explicit-any": ["error", { "ignoreGenericConstraints": true }]
  }
}

type IsString<T extends any> = T extends string ? true : false;

type CodomainOf<T extends Record<string, any>> = T extends Record<string, infer R> ? R : never;

Expected Result
No errors for explicit any if they are used in generic constraints.

Actual Result
There is no such option to disable errors/warnings for explicit any usage in generic constraints.
