What LBA format size should I choose?

I'm secure erasing my SN850 drives (after trying out Windows 11, back to 10 I go) and in the ASUS BIOS it has a Secure Erase feature. When I press a drive I get asked this:

What should I choose?

Things like this told me secure erase would be a better option.

Thanks @VersionMonkey

It also appears the SN850 drives are optimsied for 4k block sizes so seems the best option.

Although tbh the more I thought about this I don't think it matters at all. Unless I'm stupid Windows is just going to set whatever size it wants when creating the partitions.

It's an ASUS ROG board @Mcnumpty2323

It seems to be a feature in the AM4 boards for many companies.
