Question bios mode not UEFI

[Arickado]

Hello everyone, recently I bought a new motherboard so I could install the new windows 11, since I found out that my old one wouldn't work because it was not a UEFI bios mode, but after installing everything when I went to look it was still not UEFI mode.
The new motherboard is a Tuf gaming b550m-plus. I couldn't find much on the internet if is a config problem or something else entirely, sorry in advance for the inconvenience and thanks for the help.

did you do a fresh os install?
change the settings in bios?

While messing around on the bios I found a boot option for UEFI only and used the pendrive with the win11 boot install and worked, thanks for the reply everything working now.
