Question "No NVME device found" after updating BIOS of Gigabyte B450m DS3H ?

[Neodaka]

So I planned to upgrade my Ryzen 5 2600 to a Ryzen 5 5600X.

Before changing the CPU I updated my BIOS from F32 to F40 and then to F61 for Ryzen 5 5000 series support. After updating the BIOS I tried to boot into Windows from my Samsung 970EVO Plus 1TB which contains the OS and all my personal data, games etc..
I was thrown into the BIOS and my EVO wasn't listed in the boot priority anymore.
When I go into NVME Settings it shows "No NVME device found"

Steps I tried to solve the problem:

• Reinstalled the NVME
• Reverted BIOS to F32
• Booted from a windows installation stick to check if Windows can find the NVME Drive.
• Checked the NVME in another PC were it wasn't shown in Windows or BIOS either.

Specs:
GPU: Gigabyte RTX 2070
CPU: Ryzen 5 2600
Motherboard: Gigabyte B450m ds3h
RAM: 16GB RAM
PSU: be quiet! Pure Power 11 FM 750W
OS: Windows 10 Home

When you installed win10 on this SSD, was in UEFI or Legacy mode in your bios ?
After updating your bios, did you check that the bios was set in the same mode as when you installed WIN 10 ?

I am pretty sure it was UEFI when I installed Windows 10
Right now the BIOS is also set to UEFI I think but I'm not sure.
Where can I check this?

Sry for the dumb question.
