I want to have more than minimum on board DDR5 ECC, but it seems that it is removed from AsRock BIOS?

I got X670E Taichi + Kingston 32GB DDR5 4800MT/s ECC Module KTD-PE548E-32G + Ryzen 9 pro 7945

X670E Taichi has under specs: https://www.asrock.com/mb/AMD/X670E%20Taichi/index.asp#Specification Supports DDR5 ECC/non-ECC, un-buffered memory up to 7800+(OC). but has no ECC option in BIOS?!?

Searching about it I found forum posts where it was mentioned that ECC support got removed, and indeed in the manual it says: Supports DDR5 non-ECC, un-buffered memory up to 7800+(OC)

However as per https://wiki.gentoo.org/wiki/ECC_RAM dmidecode indeed reports Multi-bit ECC, and Total Width: 72 bits, and demsg EDAC MC: Ver: 3.0.0

Somebody suggested mobo automatically recognizes ECC supported hw and enables it.

Somebody else suggested overclocking and checking for corrected errors.

Any other opinions and suggestions?

It's my first ASRock build and I like it so far, except for this ECC conundrum...
