Conditional mutationFn in useMutation

Is it possible to create a custom useMutation like the following with the correct typescript ?

export const useCustomMutation = <T extends Types>({ type }: { type: T }) => {
  return useMutation({
    mutationFn: type === 'one' ? one : two,
  });

export const useCustomMutation = <T extends Types>({ type }: { type: T }) => {
  return useMutation({
    mutationFn: type === 'one' ? one : two,
  });
