@JusticeMolton Welcome to the Win-Raid Forum!
Why don’t you try to do the BIOS modification yourself? >Here< is a step-by-step Guide.
By the way - you are/were able to boot off the Samsung 950 Pro in LEGACY mode, because it has an NVMe Option ROM in-the-box (it is the only SSD with such module). To be able to boot off any other NVMe SSD your mainboard needs an NVMe EFI module.
Good luck!
