Hot take: if you go slow enough, almost any low-profile tire with stiff sidewalls can be treated as a very temporary run-flat.
I have driven 20+ miles on a completely flat rear tire, on a day that happened to be very windy. I blamed the wind for the car's squirrelly handling.
Granted this was a Miata, not a Porsche, but same idea. If faced with the necessity of stopping in a "bad neighborhood," I would put on the flashers and limp down the road a bit farther.

yep, the tire is a goner anyways, porsche will not fix a flat, replace only unless you take it somewhere else. something small gets the tire goo, something a little bigger in the tread gets both the goo and a plug, a sidewall gets a phone call.

With that said: A bolt went through the rear tire (and wheel!) of my 991.2 just 37 miles from home at the end of a 2,500~ mile road trip. No way a roadside fix was going to work, and I found myself thanking my lucky stars it didn't happen in the wilds of Nevada or Utah as I waited for a flatbed.
I now have an extra wheel/tire set, but will be assembling a full tool kit and taking a front wheel/tire with me for long trips. The 991.2 is (way) too good at grand touring not to use it that way. Other option would be to prep a wheel/tire for overnight shipping before I leave, but that may not help much in remote locations.

Unfortunately........ Miata wheel $
Porsche wheel $$$$$
In a "bad" neighborhood CALL AAA Then Dial 911 report shots heard...Plenty of cops will come and hopefully the Flatbed to tow you away before they leave...
NOTE Before y'all get bent out of shape
this is sarcasm

Interestingly, in the case I'm talking about, not only was there no damage to the wheel, there was no apparent damage to the tire. I obviously replaced it, but it was still acting like a really terrible run-flat when I finally got to my destination and noticed what had happened.

I was touring with a Cayman on a small winding mountain road when the Cayman had to dodge an on coming vehicle and incurred sidewall damage on the road shoulder. We were on a road with no cell service and too small and windy for a flatbed. The sidewall damage was bad enough that you could hear the air hissing out but intact enough to hold some air. We used the Porsche air compressor and inflated to 40 psi and drove until it was down to 25 psi and filled it again. We did that cycle 5 or 6 times. We were able to transit the mountain road and get to a main road. It was a Sunday. We parked the car in an area where a flatbed could easily pick up the car, ordered a tire from TireRack for next day delivery at a TireRack installer located 25 miles away. Piled the passengers and luggage into my 911 and we went on to our hotel for the evening. Travelling in pairs helps.

I specifically asked the Porsche dealership if the TPMS sensor would be damaged when I used their repair can, they said no problem. The can has an expiry date on it.
Best to check, so you don't have the cost of a new tire and TPMS sensor to cover.

It is a 996/7 collapsable spare ( got it from suncoast).. Fits on the front of a 991.2 GTS.
If you get a flat on the rear you move a front tire to the rear and put the spare on the front.
Track flats often destroy the tire so no plug kit will work there.

Unfortunately, PCCB dictates a full-size spare, and I need to get to work on figuring out how to secure a front wheel/tire on a rear seat. I don't see a factory solution for that, which is interesting as I think Porsche is required to include a spare in certain markets (such as parts of the Middle East, iirc).

I love the suggestion of the Dynaplug. I have a similar product in my mtn bike pouch for tubeless repairs on the trail. The design concept is brilliant for a car tire. I agree the absolute worst part is pushing the plug into a steel belted tire with the conventional screwdriver looking plug holder...I typically remove the wheel to get the best leverage at home. A rear plug on the street might be near impossible.
FWIW, for our not-so-fast cars I plug holes at home from the inevitable nails and screws causing slow leaks all the time. Far better and faster than taking to a tire shop that won't hesitate to recommend a new tire for "liability" reasons. Heck, I've got a Toyota Tundra with a plug right at the curve of the tread edge and it has been fine for over 20k miles. I would not hesitate to plug the Carrera tire to get home and then get the tire properly repaired or replaced from home.

If I was on iron rotors, this would 100% be the way to go.
