Hi noamraph: Thank you very much for joining the Intel® NUC communities. We will do our best in order to provide the information you are looking for.
In regard to your inquiry, according to our documentation there is no other way to enter the UEFI shell without enabling the UEFI shell setting on the BIOS. As you mentioned it is a requirement to access the UEFI shell. However, I encourage all the peers viewing this forum that if they have additional information or suggestions on this subject to post all the details on this thread.
Any further questions, please let me know.

The NUC, by default, is going to boot from the first available source in the Boot Order list. If you enable the UEFI Shell but ensure that the SSD/SSHD/HDD is higher priority (i.e. higher up in the list), then it will always boot from the SSD/SSHD/HDD. When you want to actually run the UEFI Shell, during boot press the F10 key (select boot device) and then select the UEFI Shell entry in the devices list.
With it configured to work this way, you can leave the UEFI Shell enabled all the time but never see it start running unless you choose to do so via the F10 startup method.
When I enabled UEFI Shell on my MY, I found that the entry for UEFI Shell was already at the bottom of the priority list and ready to work as I have explained. The only way that this becomes a problem is if you are supporting only Legacy boot devices. In this case, then yes, the UEFI Shell is always going to start. To fix this - don't use Legacy Boot!
Hope this helps,
Thank you very much! Indeed, currently we're using legacy BIOS format. It's good to know that if we move to UEFI, the UEFI shell will probably not be the default.
Your response encouraged me to learn more about UEFI, and I found this to be a very good explanation: https://www.happyassassin.net/2014/01/25/uefi-boot-how-does-that-actually-work-then/
