It was indeed not booted in the UEFI mode, as I gathered from Vultr's
tutorial[1] on installing Gentoo, the volumes should use MBR anyway, so
my attempt to use both UEFI for ISO image and installation failed as
well.

I have changed both ISO and deploy config to using MBR, now it is a
different error, so some progress at least. Thank you!

Best,
Dmitry.
