Good news -- I removed all but one of my RAM cards and was able to boot up with BIOS A, which was on 1.11 (looks like the secure backup B->A didn't have any effect). I attached a FAT32 USB stick with the 1.10 BIOS file and used the UEFI Instant Flash tool to successfully downgrade BIOS A. I then...
I found a jumper (undocumented) to switch to the backup BIOS -- D_BIOS_TEST1, located above CHA_FAN3. Now I'm able to boot into BIOS B, but I have another problem. It boots and quickly shuts down 1-2 times, then boots and does the Secure Backup UEFI B->A until the progress indicator reads 99%...
I opened a support case with them this morning, haven't heard back yet. If I can't get a resolution then I may have to go that route. Would be nice to avoid that hassle though if possible.
Right. It's been over 30 failed boot attempts now, so I'm trying to get a better idea of what they mean by "after several failed boot attempts, the backup BIOS will take over" (or find some other way to force the switch). BIOS_A_LED is still on.
That's the problem -- I don't know how to do that. There's no switch on the Z270 Supercarrier to go from BIOS A to BIOS B, as far as I can tell. There are some jumpers near BIOS_A_LED and BIOS_B_LED, but I can't find any documentation that indicates whether they enable switching the BIOS.
The ASRock Z270 Supercarrier might be a good fit for you -- it supports Thunderbolt 3 natively and has 10 SATA3 ports, 3 M.2 ports, and both USB 3.0 and USB 2.0 ports:

I have an ASRock Z270 Supercarrier and used the Internet Flash utility in UEFI setup to upgrade the BIOS from 1.10 to 1.11. The upgrade process completed successfully and no errors were reported. However, when the computer rebooted with the new BIOS, it just hung with a blackscreen. I have...
Well in particular, I'd be curious to know if it uses a different panel or not. displayspecifications.com doesn't list the specific model of the panel, just the manufacturer (AU Optronics). Whereas for the BL3201PT, the specific model of the AU Optronics panel is listed as M320QAN01.0.
Can't...
What do you guys think about the newer BenQ PD3200U model, which according to pcmonitors.info is an updated version of the BL3201PT/PH? I can't find many reviews on it yet. For instance, does it use the same panel that seems to be susceptible to glitches as reported in this thread, or does it...
