How bad did I mess up?

Long story short, had a custom efi someone did for me. And then I decided to upgrade hardware. I thought it would still boot into osx I would just need to change the efi plist anyways I swapped the motherboard and cpu+ ram and I can’t boot in. I tried to install windows but I’m showing 3 drives? Even though only 2 nvmes and only 1 to my knowledge has the efi and boot on it. So I’m hoping there is a way to fix with ventoy? As I can’t add windows to a partitioned drive and I can’t seem to get the iso file for Ventura to install on thumb drive.

Any tips? Trying to save all data most of it is not on the OS drive
