The kernel dump was very useful! I'll briefly outline my thinking and the process...
The dumps (all of them) show the following failure bucket...
Code:
FAILURE_BUCKET_ID: 0x133_ISR_nt!KeAccumulateTicks
The ISR there indicates that the excessive time that led to the BSOD was spent during the Interrupt Service Routine. This is the front-end of device interrupt processing, where the device signal that data is available by issuing an interrupt. The relevant ISR gets control (the ISR code is in the driver) and all it does is record the buffer address where the data is located, it schedules a DPC and then ends. This is where your problem is - in this dump at least.
The scheduled DPC (Deferred Procedure Call - the back-end of device interrupt processing) will be run when a CPU comes idle. The DPC code is also in the device driver, and it tells the waiting thread that the data has arrived and points to where it is. The waiting thread is then marked ready for execution again.
Using the kernel dump we can examine both the ISRs and DPCs that are running on your system and from there see which one(s) are running for too long. We use the Windows Performance Analyser (WPA) to display the results...
At the top are the DPCs and at the bottom the ISRs. We know the problem is ISR related, so if you look at the far right column (Duration (Fragmented) (ms) Sum) you can see I've sorted on that column. At the top is the longest running ISR; HDAudBus.sys, which ran for 8.6 ms (8607 μs). No ISR should run longer that 25 μs, so this is your problem. You can also see in the DPCs that HDAudBus runs for 1029 μs, Microsoft recommend that no DPC run for more than 100 μs. We have other long running DPCs, but HDAudBus.sys looks to be the problem here.
However, HDAudBus.sys is a Windows driver and so it's not at fault. It will be calling lower level third-party drivers, including the Realtek audio driver RTKVHD64.sys. The version of this driver that you have is old, dating from 2020...

You need to look for an update for this driver on your motherboard vendor's website. I would suggest you update any other old drivers whilst you're at it.
I can see that you also have the Nvidia audio driver nvhda64v.sys installed, it comes with the graphics driver. You ONLY need this driver if you are sending audio over HDMI as well as video. If you're not doing that you don't need it, and it's known to cause conflicts with Realtek audio drivers. Updating the REaltek driver may solve this however. If it doesn't then use
DDU to fully uninstall the existing graphics driver and reinstall it (or the latest version if there is one). Choose a 'Custom (Advanced)' install and uncheck the box for the audio driver so that nvhda64v.sys is not installed.
