 memtest86+ I've never tried on UEFI. For UEFI I
use memtest86, and in
/boot/grub2/custom.cfg to run it I have this head:

menuentry "memtest86 8.3 EFI" {
	search --no-floppy --label --set=root PNY5P01ESP
	chainloader /mt83x64.efi
}

/boot/grub2/custom.cfg is utilized as a consequence of my customization of
/etc/grub.d/, which quite simply moves the content of 40_custom to 06_custom,
leaving 40_custom empty.

/boot/grub2/custom.cfg contains all the boot stanzas I routinely use on UEFI, as
grub2-mkconfig places all custom.cfg stanzas ahead of its own auto-generated ones
in grub.cfg as a consequence of 06_custom content.

IOW, NAICT, 40_custom in grub2-efi works no differently with UEFI than in grub2
legacy booting.
