mutate in loop cause infinite re renders

usecase: I have orders coming from other hooks wraped around useQuery I am getting orders from those hook What i need to do loop through all orders, get few properties and fire mutation inside loop, get data from previous mutation and fire other mutation . Problem mutation causing infinite re renders (used async mutation), code 
 for (let i in allOrders) {
  
    let customerDetails = {};
    let productDetails = {};
    let orderDetails = {};

    customerDetails.name = allOrders[i].shipping_address.name;

    customerDetails.address =
      allOrders[i].shipping_address.address1 +
      " " +
      allOrders[i].shipping_address.address2;

    customerDetails.phone = allOrders[i].shipping_address.phone;

    customerDetails.pincode = allOrders[i].shipping_address.zip;
    customerDetails.province_code = allOrders[i].shipping_address.province_code;
    customerDetails.city = allOrders[i].shipping_address.city;
    customerDetails.state = allOrders[i].shipping_address.province;
   
    // want to mutate(customerDetails) here and get data from mutation 


// mutate orders (customer id from previous mutation)
}
 for (let i in allOrders) {
  
    let customerDetails = {};
    let productDetails = {};
    let orderDetails = {};

    customerDetails.name = allOrders[i].shipping_address.name;

    customerDetails.address =
      allOrders[i].shipping_address.address1 +
      " " +
      allOrders[i].shipping_address.address2;

    customerDetails.phone = allOrders[i].shipping_address.phone;

    customerDetails.pincode = allOrders[i].shipping_address.zip;
    customerDetails.province_code = allOrders[i].shipping_address.province_code;
    customerDetails.city = allOrders[i].shipping_address.city;
    customerDetails.state = allOrders[i].shipping_address.province;
   
    // want to mutate(customerDetails) here and get data from mutation 


// mutate orders (customer id from previous mutation)
}
