In ifupdown, 'manual' mode does accomplish this, yes. The side effect of this is that systemd does not block booting if the interface hasn't been enabled yet.

So the two relevant configuration knobs are:

(1) Should this interface be brought online at boot time? (default adminStatus)
(2) Should this interface be required to be up (and configured with an IP address) before the machine continues to boot? (lack of this requirement is implied by manual mode plus "auto <ifname>" in ifupdown)

We have seen MAAS bugs where these use cases have been problematic, such as users configuring a "backup bond" which is not (yet) online. (See also #1553617.)
