November 2021. 2 years makes an enomous difference. During that time there have been massive improvement in  UEFI support by the linux kernel.
Back then it was probably kernel 5.15 or so, Debian Bookworm was released at kernel 6.1 and now its just been announced that the 6.6 kernel will be the next long term release. The mainline is on 6.7.
So any custom kernels might be based on 6.6. 

I have 2 Bookworm office PC's running under UEFI and its been seamless. Some additional steps are required if you build any kernel modules. eg DKMS drivers.

PC specifics are:

HP EliteDesk G2 800 mini 65W
I5-6500 3.2 GHz
BIOS N21 Ver,-2.19 06/01/16

Ran for LinuxCNC 18 hours without issue but my test
SSD drive died  when I did a power cycle to read the BIOS
info so I probably wont do a longer test until I get a
new drive.

Interesting the unit I have is also an i5 but the 6500T model and it's rated at only 35W.

Seems like this one uses a laptop processor, hence the latency issues.
I did not check, it's just from experience.

Well at least we found the cause of the varying results, I bet the it throttles like crazy going in and out of various power states in order to maintain that 35W TDP.

Sort of funny actually, because that's the power supply I got with
my ebay 800 G2, and it will not run the PC, you get a beep error and
no bootup. I had to borrow a 135W supply from another HP Elite
to do the test...

And mine is a 65W, which explains why I didn't keep seeing EFR's once I sorted out the 7i96s 5v power supply.

What is the current status of bookworm / kernel 6.1 and realtek dkms driver ?
Is better 6.6 kernel for read error?
