[REQUEST] Maximus XI Gene remove Spectre/Meltdown

hello, could you help me remove or downgrade the microcode in the BIOS? I will be glad for any help, my 8700k processor myself, I can not master it, I saw a similar topic but on the apex
if it can be done then in bios 1901
I can’t leave links for BIOS, but I think it’s not a problem to find it through Google, Thanks
