Have a try to download from www.st.com: STM32CubeH7 - STM32Cube MCU Package for STM32H7 series (HAL, Low-Layer APIs and CMSIS, USB, TCP/IP, File system, RTOS, Graphic - and examples running on ST boards) - STMicroelectronics
Then rely on Hep > Manage Embedded Software Packages. Use "From Local ..." button helping to install properly package you'll get from www.st.com
