Thanks for the idea @CoolBook ,
In addition to the previously mentioned changes, I've disabled thermal velocity boost, as well as adaptive boost, and I've lowered the V/F point for 7-11 by -0.001.
I also capped all of the performance core ratios down to 55 max from their default 60 max ratio.
So far this seems to have Greatly improved system stability and application stability, prior to these changes I couldn't even open steam or discord without them crashing immediately, I will still need another RMA to attain standard CPU speeds and stability on standard settings again, but at least with these settings I can use my PC again normally in the mean time! (So far). I'm awaiting reply from Intel support regarding another RMA. I hope they're not too short staffed after the recent layoffs.
For others: I found the information I gathered below helpful in figuring out how best to slightly undervolt and underclock the i9 14900k for stability.

(Make sure not to accidentally overclock anything with positive offsets if you're having stability issues, as this could void your warranty).

I will continue to test and tweak settings for stability as needed.
Please do let me know if you find other/better ways to increase stability in the bios!

Time for an update as to my issues regarding this post.
At the end of May I had RMA'd my last processor. After installing the RMA'd chip, the system was stable for a few months. (After heavily modifying the BIOS settings utilizing an intel recommendations graph).
After installing the latest BIOS update that's supposed to be a preventative fix for this issue (with some microcode adjustments), it's now randomly blue screening with the same errors, and on top of that applications are randomly closing themselves out more often and in an even worse way than before. Tabs are crashing on Firefox repeatedly, NTFS.sys just popped up with a blue screen as I'm writing this, and with multiple browser crashes. Recently tonight there were also a couple of page fault in nonpaged area bsods. All of which were related to my CPU issues last time around and resolved themselves temporarily after the RMA.
It looks like I'll need to RMA my chip again.
I read online that Intel is providing another round of RMA replacements for affected users, and that sometime around mid-August there should be another BIOS update released that should help alleviate these problems for any CPU that has not sustained permanent damage from this fault.
(I may look into checking to see if some of the bios settings I had in place were reset after the last bios update, for those looking for these recommendations, Check out the Image posted in the Intel forum user posting linked here, and in the image shared below:

Good luck to you all, and hopefully I can get this issue resolved again in a more permanent fashion.
Alright, so it looks like my settings did get wiped after the Bios update, I have reimplemented them, and stability and usability have greatly improved once again. For those having issues with their i9 14900k or similar processors, I will post the changes I have made in my BIOS that have made an improvement. I imagine these may also help with other 13th or 14th gen intel processors experiencing similar issues. I mostly followed a guide Falcon Northwest had put out, with my own flair and tweaks for my build, since I'm prioritizing stability over performance. I will share those images as well. If these settings don't help you, you may need to RMA, as I had to once.
May the silicon be ever in your favor.
Using Battlefield 2042 to test, temps are high, but it's not crashing!

So according to HWinfo, 1.627 V Requested by a core. (Not the voltage really supplied by the voltage regulator, the tooltip says)
To all: I'm still getting an occasional firefox tab crash and having to reload them a couple of times, not nearly as bad as before. Hopefully it's just some mild leftover page data corruption that will be cleared if I clear the Firefox Cache, and not the start of further significant issues.
