Hi Francisco,
Welcome to Microsoft Community.
It sounds like your SSD and internal disk are not recognized in the BIOS when you install Windows on your Surface Pro 11.
Based on your description, it looks like you are using Windows installation media, you should download the recovery image created for Surface and use the recovery drive for Surface to reset it to factory condition. Creating and using a USB recovery drive for Surface - Microsoft Support
For Surface, especially Windows Arm-based PCs, you need to use a recovery image file specifically for Surface devices.
Your Sincerely
