I bet you it’s because of the intel RST settings in the UEFI. If RAID is turned on the RST driver is needed. Ive ran into this exact same issue, not being able to see my drives when installing windows. Swap over to AHCI and the windows installer should see the drives.
Note that changing that setting can cause problems for existing OS installations. Make a backup and do your research before changing that.
