[Request] Unlocking BCLK after updating bios (skylake/kabylake)

Hello, thanks for reply.
Im not 100% sure which version of bios i had previously, but I think it was 0602:

For now I have the newest one 3805. You say version 8001, but which one is it (I do not see it on the Asus website).
Sorry my mistake, last one with BCLK was 1805 (that’s the last version that AMIBCP shows function “BCLK frequency”).

I know that ASUS has locked bios’es, I was looking through this quide made by @rofikkernel GUIDE (he used Asus motherboard as example, he also did video to this guide).
I was also looking at this GUIDE
And this guide regarding flashing GUIDE
and Here Lost_NBios also explained a lot regarding activating BCLK funcionality LINK

It’s not a problem for me to buy a hardware programmer, I was already considering CH341a (it should be ok right?, bios chip is Winbond and it’s removable from mb, no soldering needed).

So I assume, can I make backup/dump using methods mentioned in those guides and then maybe try to flash with ch341a (of course after taking your hints into cosideration)?
