You'll need to reinstall, I think. According to [1], ESP on RAID is not
a good idea, which means one of your drives will have to host the EFI
(and also usually boot) partition.

Instead, you can do something similar to the full-disk encryption /
plausible deniability setup I experimented with a few months ago [2] --
host the EFI / boot partition on a high quality USB drive instead and
keep your RAID array intact.
