Not any of the modern processors, no. Only some old ones could be unlocked.

And didn't that also involve motherboard manufacturers to release a special BIOS that lets you do just that?

Depends on how far back we look, like e.g. there were some CPUs where you could use a pencil to draw a line between certain traces on the CPU to unlock the CPU. But yes, some mobos offered such an option right in the BIOS as well.

In some modern CPUs (e.g. Skylake), you can make some progress with a BCLK overclock instead of cranking up the multiplier like you would on an unlocked CPU. But I doubt anyone has figured out how to unlock the multiplier on modern "locked" CPUs.

You can always go with boost clock based overclocking,but it's limited to the max turbo speed.
