XPS 13 high-pitch beeping & 3 repair attempts

I got a XPS 13 2 in 1 that I received on Feb 13th of this year.
I noticed immediately a high pitch beep going out of the right side. I did some research and found nothing about it online. It happened rarely and wasn't all that loud so I didn't think much of it. Over time it became more and more loud and frequent to the point that I stopped using the laptop completely because the random high pitch half second beeps would scare the *** out of me (I would literally jump out of my seat and swear. I wouldn't be surprised if it was near 100 decibels at this point since my girlfriend heard it on the opposite side of the house 4 rooms away).

I exhausted everything I knew to try and by this point I noticed some forum posts about this issue so I contacted support on April 3rd thinking it was now a known defect and not something that a new driver or firmware update would fix (my reason for waiting, I did buy the laptop the 1st day it came out). They gave me a list of things to try (stuff I already tried, I've worked in IT for nearly 20 years). I ship the laptop out to Dell for the 1st time. I tell them it's likely a hardware issue under the enter/backspace key. I hear it even with the speakers at 0%.

I get it back and all they did was reinstalled the OS for some reason.

The issue was still there (because it's a hardware defect) so I sent it in again.

I got the laptop back the 2nd time with the motherboard replaced. The issue was still there along with a dead pixel on the screen that wasn't there previously. I talked with support many times and sent pictures of the deal pixel and eventually they said they would replace the screen as well. I shipped out the laptop for the 3rd time and put all this in the work order.

I got the laptop back a couple days ago for the 3rd time and they stated that they replaced the plastics and the hard drive. The beeping was now much quieter although still audible. It's about as loud as a spinner drive. The beeping was quieter when I first got the laptop as well, this was my reason for not reporting this issue within the first 30 days. They didn't replace the screen because the dead pixel was still there along with many more dead pixels. I counted 9+ deal pixels and sent pictures of each. The L in the DELL logo on the top of the laptop was missing. The bottom of the laptop is all scraped up in the center and around the screws from being worked on.

I emailed Dell with many images of all my issues. After a couple days of no response I called Dell but was transferred between tech support and refunds department that couldn't do anything to help me besides more repairs that will inevitably fail or put more wear and tear on the laptop that I have barely used. They could keep doing this until my warranty runs out and I'm screwed so I did some research.

I believe this should be covered under the Song-Beverly Consumer Warranty Act a.k.a. Lemon Law but no one at Dell seems to understand California state law nor do they have the authority to issue refunds past the first 30 days.

Besides the loud beeping, dead pixels, and overheating causing throttling the laptop has been awesome but at this point I'm sick of looking at. I'm sick of shipping it out and reinstalling my apps. I haven't used the laptop in nearly 2 months due to these issues meaning the laptop has been unused more than I've used it. Dell doesn't seem to think my time is worth anything. I got the laptop for travel but I went on vacation and didn't have my laptop.

I'm not sure what to do at this point. Hopefully posting this to a public forum will make this issue more visible. Here is that forum post with others having the same problem, this is clearly a hardware defect and some people there are having similar problems with it not being resolved.
