no. that would be not industry best practice and uneconomical sw effort.
remember this devices are mainly "designed for windows" and WHQL certification

yes. the sheet for design recommended cypress chips state all ATACB and ATA-Security.
i would be make no sense to implement different behaviuors in chips for the same purpose.
