Is the High pitched whine after shut down normal?
Not sure if this is normal, but after I shut everything off on my 23 F3-T, there is a high pitched whine. Anyone else experienced this?

Yes, it is normal. The ECU keeps the throttle body slightly closed after shutdown. Since it is a 'Fly-by-Wire' system (electric motor actuates the throttle body butterflies). What you hear is that motor whine. I don't remember the time interval. But it does time out after a bit and the whine goes away.

On the early Spyders, it's something like 30-40 minutes... Not sure it's quite so long on the later Spyders tho?!

I wonder if it is some sort of calibration procedure?

I misspoke on post #4. The throttle body servo holds the butterflies CLOSED, not open. (edited & fixed)
I believe the startup default setting is 8 degrees open. Which previous, cable controlled Spyders used. The reason BRP did this with all Fly-by-Wire models, I've been told, is that leaving the throttle body open allowed residual fuel vapors to migrate creating a possible explosive mixture. Supposedly, there was a possibility of Run-On or even fire, in extreme cases.
I can't verify the 2nd answer, but the Closed vs Open, that is for sure.

So, my Spyder has been sitting in the garage for 1 hour and 15 minutes, and it’s still making the whining noise.

I never owned an F3 but I'd hear a high pitched whine every time I'd shut down either of my RTs. Turns out the whine was coming from me.

So, the noise I was hearing was the gas tank venting. Another member suggested I check that, and it immediately stopped when I opened the cap.
