Ubuntu 22.04.1 AMD GPU Driver isn't loaded although it is installed

I have installed AMD GPU Driver using amdgpu-install_22.20.50200-1_all.deb(downloaded from amd.com) and following this guide.

But I found that my display setting changed to 2560x1440 93Hz and I couldn't change it.

I tried sudo lshw -c video and it said UNCLAIMED.

$ sudo lshw -c video
  *-display UNCLAIMED

I checked my kernel version too.

I'm trying to dual boot Ubuntu 22.04.1 and Windows 11.

Fast Startup, Secure Boot, TPM 2.0 enabled.

I modified bcd bootmgr path as grub.

I already added radeon into /etc/modules. I already configured /etc/X11/xorg.conf like below.
