The option to set authentication-order as 'none' in an access profile is not available on SRX300, SRX320, SRX340, SRX345, SRX380, and SRX550M SRX platforms that run:
Pre-20.3R3

Forcing the option 'none' through CLI leads to the error message "Warning: value none ignored: unsupported platform (srx320)".
