echo 'device_specific' >"/sys/bus/pci/devices/0000:1c:00.0/reset_method"only works (and is only necessary for) kernel 5.15. If you are using 5.13, you can ignore this line and/or this error.
Your error about
echo "0000:1c:00.0" > "/sys/bus/pci/devices/0000:1c:00.0/driver/unbind"indicated that amdgpu is not loaded for the GPU, which is essential for my solution. This indicates that you are not doing the same thing as I do. You can check is amdgpu is loaded for the GPU using
lspci -ks 1c:00.0.
Please note that my setup fixed a different error than
Failed to mmap 0000:1c:00.0 BAR 0. Performance may be slow. For me, it fixed
BAR 0 cannot reserve memory(or something), which only occurs with kernel 5.15. Maybe I misunderstood your question and/or original problem, and my solution won't help you at all. Or you need to switch to the latest pve-kernel-5.15 and make sure amdgpu is used before running the script (and vendor-reset needs to be installed).
amdgpu seems to be loading and I am on kernel 5.15. See below:

I guess its different for the RX580. I can revert the changes and go back to 5.13 if necessary. I wonder if they will fix this for 5.15+
