That's because the only SNMP v3 authentication algorithms supported (on either IOS or NX-OS or ASA software) are MD5 and SHA1.

The SNMP v3 encryption algorithms support up to AES-256 (on NX-OS and IOS) and that is selectable in the SNMPv3 credentials settings on LMS.

That applies even on the latest updated Prime LMS Version 4.2(5).
