You most certainly can as long as you have some way to select the boot
method. You cannot use the same partition both as ESP and BIOS_grub,
that's true.
From a boot system of *another* disk or usb?
Certainly not a boot system from that same disk, can it?
A bios-grub and a efi-grub residing in the same disk? Possible?
What OP can do now is to make this disk fully uefi (without reinstalling
OS). Create a /boot/efi partition (or use this bios_grub - partition is
big enough), make a /boot/efi entry in /etc/fstab. Redo grub-install (in
uefi).
