Hi,
I haven't added anything easy to do that because I had some cases where the PC wouldn't boot up anymore. Anyway, it's documented in https://wiki.archlinux.org/title/AMDGPU#Set_module_parameters_in_kernel_command_line
The file you need to edit is in /boot/syslinux/syslinux.cfg if you boot in BIOS, or /boot/EFI/syslinux/syslinux.cfg for UEFI.
Now, remember that if you're on KMS, there is no modeswitching on Vulkan possible so you loose all the benefits of GA, you may need to switch to X (where I hope Vulkan can modeswitch).
Thank you ,and I have sucess
I open the /boot/syslinux/syslinux.cfg， and add (radeon.si_support=0 amdgpu.si_support=1) at the end of the line(append root=/dev/disk/by-label/GA rw quiet rd.udev.log-priority=3 splash mitigations=off audit=0 monitor=************** )，and save，reboot。It worked
