This is the correct driver that solves this,
I got it from Lenovo support and the installation went on smoothly,
after trying everything on this thread, which failed:
In new Free Dos models if the SSD isn't recognized during windows 10 / 11 installation,you can load The Intel® Rapid Storage Technology (Intel® RST) Driverdownload from here:https://pcsupport.lenovo.com/bg/en/products/laptops-and-netbooks/3-series/ideapad-gaming-3-15iah7/82uj/downloads/driver-list/component?name=Storageafter download run the exe file – choose extract – the driver will be extracted to C:\Drivers –Intel Rapid Storage Technology Driver (marked in green)and move the extracted folder to the installation USB drive
in the installation process when the source SSD is missing press "load driver" – (marked in orange in the pic below),
