Recent Dell firmware on Precision 5680/5690 breaks Ubuntu

Hello. I work for a company that purchases Dell Precision laptops exclusively. Our company has a custom image of Ubuntu 22.04 that we use, and it's been pretty solid.  Recently the Precision 5690's came out and we've noticed a lot of strange behavior on this model. There's been a great deal of weird (but reproducible) issues with Webcams not working, sleep issues, audio devices not showing up or showing up as dummy devices, incompatibility with the Nvidia driver (especially with any machine that's got A2000 graphics), etc. When even doing a clean install of Ubuntu on this model, the same strange behavior persists.  What's making matters worse is that we're noticing that last year's model, the Precision 5680's, are starting to exhibit the same troubling behaviors well. It seem like the 5680's which have been stable under Linux in the past are now behaving just like the 5690's when the most recent version of the Dell firmware is applied to the hardware. Our Helpdesk staff has noticed that any machine that shows the Dell "SecureBios" logo on boot will have these issues. All the 5690's came with this revision of the bios, but the 5680's are slowly receiving this bios revision through firmware updates pushed out with the OS updates. The last few weeks have been an epidemic of user tickets complaining of various Linux hardware related issues. Thunderbolt docks are especially problematic. Is Dell aware of these problems? Is there a fix on the roadmap for Dell's firmware? Thanks
