You are showing Xorg.log output that tells you it misses the amdgpu DDX. I.e., install and use xf86-video-amdgpu.

Yes, amdgpu kernel module and amdgpu DDX

What do you mean?

Depends what the boinc client uses. OpenCL - you will need graphics/clover which is not officially supported by AMD but may work. ROCm/HIP - won't work.
