I run a Xen virtual environment of with PVH guests.

I've built a grub2 image that loads the grub config from the guests disk so that grub can boot the correct kernel from that guests disk.

This works great with distro's that use unmodified versions of grub2 but if I try to use a distro like CentOS 8 I run into problems because they look to have patched in something called blscfg and what ends up happening is I get the error /boot/grub/i386-xen_pvh/blscfg.mod not found.

I'm curious if there is a way to build a grub2 PVH image that would load grub2, it's config and modules from the disk?
