Yes, you do have to ask that question, dummy.
Just look at every single newer generation x86 CPU. Until direct support is added in the kernel (which usually happens early on because Intel and AMD use a singular architecture for each generation so support is easy), shit's so broken it won't even boot.
You don't need to download a closed source binary blob from the vendor
Except, you know, the CPU microcode package, the GPU drivers, the WiFi, Bluetooth, etc. firmware (via the linux-firmware package), and the list goes on.
Buddy, we've already established that your knowledge of Linux et al is surface level at best, why are you still digging your own grave with verificably incorrect/incomplete statements that literally move the goalposts of this debate every time you reply?
