Seems you are out of luck. Using the wonderful Debian code search:
https://sources.debian.org/src/systemd/236-1/src/shared/ask-password-api.c/?hl=386#L380
it seems the password entry routine either prints each of the
password's characters in clear (&c) when the ASK_PASSWORD_ECHO
is set, or it prints a star "*" otherwise.
So you might try to write your own agent, or file a wishlist
bug.
But perhaps I'm overlooking something. After all, I'm the absolutely
wrong person to answer questions about systemd...
Cheers
