No, you can use modules even without an initrd.

No, these blobs are given as examples. They vary per GPU models and in
fact there are several hundred different blobs available:

ls -l /lib/firmware/amdgpu | wc -l
479

So you have to figure out which ones you need. The easiest method is to
let the kernel load them itself by having the driver built as a module,
otherwise it may take several iterations of modifying the
CONFIG_EXTRA_FIRMWARE value until you get it to work.
