you can use X-CUBE-AWS version 1.4.1 (not 2.0.0)
click on "get software" then selection previous version 1.4.1.
This version uses "AWS IOT C SDK" to connect to AWS.
If you prefer to use "Amazon FreeRTOS" then download the official version from Amazon (https://github.com/aws/amazon-freertos). It provides a B-L475E-IOT01 port directly under vendors/st directory. Follow the Amazon documentation to use it.
