summary for workaround via kernel parameter to blocker loading:

  modprobe.blacklist=hibmc_drm

**prevent load during install
To add "modprobe.blacklist=hibmc_drm" kernel parameter in grub when boot from d-i iso (press ‘e’ key and then press F10 or ctrl+x ( those key was noticed on the screen). It would prevent this module to load and let you install as usual.

**prevent load for installed system
Although, we didn't find any issues for X-window during our testing. If you want to prevent loading on a finished installed system. You can add similar setting to /etc/default/grub for line as:
GRUB_CMDLINE_LINUX_DEFAULT="modprobe.blacklist=hibmc_drm"
You need to update grub by "sudo grub-update" and reboot to make it be efectly.
