Ran into the same problem with my Alienware x17 R2, the keyboard randomly dies completely. It's obviously a hardware issue, because when it happens, it doesn't even work to access the BIOS. The only fix is to disconnect the battery from the motherboard and then reconnect it, but it'll break again after a while.

The really terrible part of it is that this only started happening after I paid Dell to replace the motherboard (because the laptop was randomly locking up, which replacing the motherboard fixed). So I'm guessing it's a motherboard issue...but apparently Dell only warranties their replacement parts for 30 DAYS? And I didn't message them until two months after the repair, since it was happening more and more frequently. And now they want me to pay for an entirely new repair and new motherboard if I want them to fix it, even though they installed a faulty motherboard in my laptop.

Started your own thread since you have a different model. To receive assistance from Dell support agents they need to first verify the ownership and warranty status. Click the blue "Get Help Now" on the right to start a private live chat session. Share the private x17 R2 Service Tag with them.

Curious, per the x17 R2 drivers page, did you install the older 11/14/22 Per Key keyboard firmware or 11/14/22 Cherry keyboard firmware (whichever keyboard you have), reboot when done, then install the 2/20/2023 generic keyboard firmware?
