AFAIK, you cannot have CPACF partially enabled.
So either you have all features of CPACF available or none of them.
Note: feature available does not mean it will be used by other software.
Regarding CFB - this is parameter of various crypto services. Some of
them do require specific machine level.
Indeed, for some services CFB is not supported on z10 (it depends on
microcode).

I have searched the archives but not finding the specific answer I need. We
have feature CPACF (#3863) on our z10-BC 2098 (zos1.13) but I am told that CFB
(Cipher FeedBack) is not enabled on our CPACF. I looked at out HMC Activation
profiles and can't determine if CFB feature is enabled but appears crypto is
enabled. Can one point me in the right direction to get the info? How is CFB
enabled? And how do you determine if it's enabled or not?
I do see this in the TN3270 start up.
System SSL: SHA-1 crypto assist is available
System SSL: SHA-224 crypto assist is available
System SSL: SHA-256 crypto assist is available
System SSL: SHA-384 crypto assist is available
System SSL: SHA-512 crypto assist is available
System SSL: DES crypto assist is available
System SSL: DES3 crypto assist is available
System SSL: AES 128-bit crypto assist is available
System SSL: AES 256-bit crypto assist is available
System SSL: ICSF services are not available
