Steps to reproduce:
Open Orion Preferences > Privacy and disable the "Enable passwords autofill" option. Close the Orion window. Open a new window and select any login form. The autofill password icon still appears in the input field, but clicking on it does nothing.

Orion and macOS:
Orion 0.99.109.1.2-beta (WebKit 613.1.12)
macOS Version 12.1 (Build 21C52)
With "Enable passwords autofill" disabled, a login field should look like this:
But currently it appears with the autofill icon still, which does not do anything on click:
