I think most (if not all) of dogleg is done by the S2. You really want to leave the atmosphere as fast as possible. Once you did that, you can add velocity much more efficiently and in pretty much any direction.
Just scooting past West Palm Beach is ~14 degrees east of south.
(That's going to shut down air traffic from at least West Palm Beach, Fort Lauderdale, and Miami. Airlines are going to complain.)
Is it possible for the second stage to turn through that plus the ~7 degrees to the SSO inclination?
Twenty or so degrees doesn't sound excessive.
The vector math isn't that complex, but the answer isn't intuitively obvious.

SAOCOM 1B begins its journey to spaceThe transfer will begin with the departure of the satellite from the INVAP / CEATSA facilities, in San Carlos de Bariloche, in a truck convoy that will transport about 42 tons of equipment to the airport. There they will be loaded on the Antonov AN 124 aircraft, which will take off from Argentine soil on Saturday 22 at dawn, bound for the SpaceX company facilities in Cape Canaveral, for preparations for the launch, scheduled for March 30.

Ben confirms March 30th and says it will likely occur around sunset EDT. It'll also be a RTLS booster landing profile.

That sound you just heard was every aspiring launch photographer on the east coast making travel plans. Launch, polar orbit dogleg, and booster RTLS, all at sunset? Yes please!

https://twitter.com/conae_oficial/status/1230951167649370112 So we loaded the #SAOCOM1B on the Antonov AN124 plane
The procedure was performed in two phases. The two ends of the plane are opened, the satellite is loaded from the front and, from the rear, the solar panels and the support equipment.

Interesting... I'm actually going to have my family with me for spring break and already planned for the KSC visitor center that day! I realize there's still a fairly good chance of a launch date slip this far out, but I may have to see if we can hang out until sunset before heading back to Orlando.

Launch time is 23:21 UTC (7:21 p.m. EDT) on March 30.
https://spaceflightnow.com/launch-schedule/
It should be 00:21 UTC on March 31
I believe the time is correct (March 30, 23:21 UTC). This is after USA switches to DST, so Florida is UTC+4 instead of UTC+5.

SFN now has the launch time as 7:21 pm EDT = 23:21 UTC on March 30, about 20 minutes before sunset.
