Lots of people having issues with their 2013 Mac Pro rebooting during sleep, sometimes while working. This post: https://discussions.apple.com/thread/253344367?answerId=256829636022&login=true&page=1 was marked solved, but it's not.
Same Mac, same for me, it appeared after the upgrade to Big Sur.
Looks like it's related to USB / Thunderbolt 2 devices. The less they are, the less it reboots. With just an USB Apple keyboard and 2 USB SSD hard drives (all of them directly connected to the USB ports of the Mac - no hub), mine almost doesn't reboot. Still some MCA errors here and there, especially during the night.
If I need to connect another USB or Thunderbolt device, I make sure to disconnect it before putting the Mac to sleep.

Anyway, this is clearly an Apple problem. If not, why since the upgrade ? And they certainly won't do anything for it since these Macs are at the end of their life :(
I'm having the same issue for more than 2 months, after upgrading to Monterey I assume.
After seeking solution for a long while, I did a full disassemble of the machine, cleaned up all the cooling system including re-applying thermal paste and POOF. The problem is gone, at least was gone for 2 weeks, until now. Today I came back home and see the same issue again.
So, it seems the problem is overheating on the CPU but I don't know what causes that, I have a brand new cooling system and there was not any apps running to cause an overheating issue.
Just make a separate partition and install Monterey, then you can delete it and use Big Sur with the new firmware / or install it on your Apple SSD and then put back the SSD with the Big Sur in
It is very easy 😉
and there is still no sign of apple support in sight. There are more and more cases that the crashes only happen after installing Monterey.
Dammit - decided to reinstall as there was so much clutter after 9 years. But was otherwise having no issues. Now a "clean" machine on 12.2.1. , and dealing with this. Regret. Those fears of potential problems of fresh install have been realized.
Before writing here, I read all the previous 5 pages discussion and tried everything suggested by everyone, but I too still have the same issue on a MacPro 3013. The issue appeared after the upgrade to Big Sur.
And I too have an external 1TB Thunderbolt SSD (LaCie rugged). But I cannot avoid using it, because it contains all my "work in progress".
Thanks for the good news !
I read the macrumors thread you linked to, but it refers only to a Monterey update. It's unlikely that Apple includes this new FW in a Big Sur update for those like me who don't want to upgrade to Monterey for the moment. And it looks like there is no way to update the FW separatly from the OS.
Ok, thanks for the tricks ! The only thing is that my internal Apple SSD is almost full and then I can't partition it. I have a mirror backup of it (made with CCC and allegedly bootable) but I'm not sure it will still be bootable when copied back to the internal SSD since Apple changed the booting rules with Big Sur.
I got this adopter

and am using a standard NVMe SSD.

My mac pro 2013 did this last night. I have one thunderbolt device an OWC Thunderbay 4, running Big Sur 11.6.4.
My Mac Pro (Late 2013) at macOS Monterey 12.0.1 Still random reboot
Interesting, thanks. Just wondering if it's possible to boot from an external SSD (or USB key) with Big Sur in order to be able to format the internal NVMe SSD with this adapter.
