The car is new to you, I presume? Do you have stock pads/rotors? How many miles? Any brake work recently? How would you describe your driving style? Relaxed, moderate, aggressive?
There's a fair bit of posts that mention "squeal" in the 991 section. Do a search and there should be some leads you can follow. Some tips include: Get under the car and check for debris/rocks stuck between the rotor and shield. Do a good brake bedding procedure (search, or try this: https://www.zeckhausen.com/catalog/i...Path=6446_6443).
If none of that works, you can try different/aftermarket pads. The track guys here (I am not) should jump in and be able to suggest some alternatives.

Is it a stock pad? I have zero squealing with those but track pads are pretty bad. Are your clips still strong - if there have been many pad changes they will wear out. you could try something like this between the pad and the caliper pistons. I use anti-squeal...
There are some DIY threads on changing pads; check those out. Fairly easy to pull your caliper - would recommend you get a box or something about 8" high to rest the caliper on if you do decide to pull them. You will also need a few specific tools like a torque wrench, a 10mm torx socket to pull the bolts, jack, jack pads, etc to do the job. Just pay attention to the abs clip as if you pry that wrong, you can break the clip...which is no bueno.
If you plan on keeping the car for a while, get the few necessary tools to do this an oil changes. You'll save yourself a bunch of dough.

The car only has 4000 miles so I am guessing it has stock pads and its the standard steel brakes not the carbon brakes.. I have all the tools to work on it and can't wait to turn wrenches on it.. Already changed the badges and getting the windows tinted. Then it's engine mod time after I get money put away. I think just upgrading to composite pad might help.
Good deal and congrats! Note that I've had my car for almost 4 years, 33K miles and have never had a peep out of the stock pads. Other pads (like ds2500) are better in many ways but if noise is your issue, you can probably fix that with the anti-squeal for $10ish.

this is porsche’s answer to that. whenever i get a little noise, ill go on the freeway when its clear and do a couple high speed emergency stops. 100-120mph slam on the brakes as hard as you can until it slows to maybe 30-40 mph. usually works and stops making noise after that.

totally normal, and anecdotally I've never had performance brakes that don't squeal. your owner's manual even talks about it, as well as the marketing videos porsche posts as in the previous post.

but some spirited driving and hard braking will help.

A couple hard slow downs from whatever speed you’re comfortable with to 20 mph will probably be all that’s needed.

agree with others here regarding stomping on brakes hard a couple times. use mine as a daily driver so it spends a lot of time around town/in traffic. have gotten the squeal's a few times and 2-3 hard stomps takes care of it.

15k on the stock pads and just a very rare hint of squeal.
When washing the car, the brakes get a good hosing, hard enough pressure to rinse away the loose brake dust. This may or may not help.
