Ok, I'll admit that I'm a touch confused. What leads you to believe that 
the microcode is out of date?  The firmware load line in dmesg is:

loaded firmware version 83.e8f84e98.0 ty-a0-gf-a0-83.ucode op_mode iwlmvm

Isn't the firmware version a factor of the kernel being used?  In my 
case, 6.5.0.  And if so, wouldn't that imply that you don't just choose 
or change firmware versions unilaterally?


The "Microcode SW error detected" is one example of Wi-Fi trouble in the 
system logs.  Other occasional signs of trouble include:
iwlwifi 0000:01:00.0: Unhandled alg: 0x707
iwlwifi 0000:01:00.0: WRT: Invalid buffer destination
