Does HAB work for non-secure parts?

I see that 'Secure Fuses' and CAAM/Cryptography module are listed as an optional for the 'secure parts'.  However, the chips always have a boot ROM.  Will the Vybrid read the fuses for srk/etc and perform a HABv4 boot to authenticate images or does it always boot in an 'Open configuration' if the part is non-secure?  It seems possible that the HAB could use a software algorithm to verify images if the CAAM is not present or maybe this feature is not supported.
