[Request] 11th Gen CPU support to Asrock H470M-HDV/M.2

[kokegar]

Hi everyone this is my first post. Today I've received my "new" 11600k cpu,  I thought all LGA1200 motherboards were compatible with all gen11 cpus but sadly discovered it was not compatible with my motherboard ASROCK H470M-HDV/M.2. The error I get is black screen, no image but fans turn on. 
I've been looking all day online for some information about BIOS modding but I'm not sure how to proceed.
Some asrock motherboards with same chipset received a BIOS update to support gen11 cpus but not mine.
For example H470 Steel Legend with BIOS 1.40 GEN11 was not supported but with BIOS 1.60 it is supported.
Same for H470M-STX BIOS 2.00 unsuported gen11, BIOS 2.10 with gen11 support.
I have H470M-HDV/M.2 with the latest official bios: BIOS 1.40
Any help would be appreciated, if I'm missing anything or did something wrong please let me know. Thanks in advance.
