Dell R730 ZFS on Root Doesn't Boot in UEFI Mode

I have a new (to me) Dell R730 with 15.1-RELEASE. I have a single stripe zpool. I am using the mrsas module. When I installed the system at the outset, I chose ZFS root and I elected to partition with GPT +BIOS +UEFI. When I did the installation, I used BIOS mode. I had planned to transition to UEFI mode later, thinking it would be easy. I was eager to get something going and BIOS mode got 'er done.

I am able to boot with BIOS mode set in the Dell BIOS. I am also able to boot the system with UEFI mode set in the Dell BIOS with a roll-yer-own portable USB installation with UFS.

What I cannot do, is boot with UEFI to the ZFS zpool.

I've tried a lot of things. The most germane being the boot code steps here: https://wiki.freebsd.org/RootOnZFS/GPTZFSBoot . I really thought that would do the trick. Now I am at a loss.

The Dell BIOS fails to locate any part of the FreeBSD boot process in UEFI mode.

I wonder if this is like one of those old SCSI systems where I have to feed the boot process a driver early in the boot process. Those days are long past. I'm guessing at this point.

FWIW, this box is for tinkering. I plan to run lots of jails and to learn something about all the high availability features in the box most especially being mean to my disks to learn ZFS the hard way.

Question remains, where exactly does it stop? It'll be a bit of a chore to type the whole error, can you take a picture with the exact error?
