use query hook react Apollo conditional call

You should use skip option:

If skip is true, the query will be skipped entirely.

const isBroncos = getCondition();

const App = () => {
  const [player, setPlayer] = React.useState(false);

  const { data } = useQuery(GetBroncosPlayersQueryDocument, {
    variables: { player },
    skip: isBroncos
  });

  return !isBroncos && data && <>...</>;
};
