Guessing here, but I'd be hard pressed to think of how you could heave
to with a Nonsuch.

Also difficult to do with a Freedom rig 'cause it'd require some
special effort to back the jib. (It tacks on its own.) Maybe you could
attach a line from the clew to the toe-rail or something to prevent it
from tacking before you go into the tack-and-lock-the-helm-over
procedure.

But so what?

[Opinion alert] Heaving to belongs to the era of wooden boats, hemp
lines, and canvas sails. It's been lovingly preserved and practiced by
"blue-water cruisers", i.e. folks with full keels, low aspect ratio
sailplans, roachless and battenless mains, etc. It's not a technique I
have ever used or ever intend to use.
